To not go to engagement party because I’m jealous?

You sound utterly miserable. To not go to dp bro engagement isn’t nice. But you’ve found every excuse to be jealous of her and what sounds like, hate her for what she has.

Oh dear op. The green eyed monster has got you, which is understandable to an extent and certainly very human, but also destructive. Comparison is called the thief of joy for a reason. You need to stop looking at their social media for a start, and not go to the party if you don’t want to. You are also so young to be saddled with an unsupportive twat, maybe take some of the time you save on avoiding social media to consider whether he’s the guy for you..

None of your problems are her fault.

22 is spectacularly young to have a baby let alone IVF. You have years and years for all that. If you go ahead with this man you'll end up on your own and penniless.

Your partner isn't very supportive of you and you seem to disagree on some basic important things - marriage.
While generally I think you need to get over your feelings of jealousy, this woman does not sound very nice and I agree avoiding her is best for you. Make your excuses about the engagement party and distance yourself from the couple as quietly as you can. It might be a challenge if your partner is heavily involved in the wedding. I recommend saying as little as possible about them to his family.

22 is crazy young to be having kids and getting married in my opinion.
I understand your fertility is an issue but I still wouldn't be rushing into having a baby with someone I wasn't 1000% sure of.

With regard to social media. Do not follow that woman's account and stop her updates on FB. Her life is not normal and don't compare your life to her life.
Your life is normal.
A huge number of people have fertility issues, you are not alone in that.
Most of us do not live exciting lives traveling the world with babies in tow, no matter how much money or how many houses we have.
Most people work bloody hard.
Life is not easy for anyone, don't let the apparent gloss of one persons life fool you.

If you want marriage so badly that you resent and are jealous of this woman who has done nothing to you but just happens to be your partners brothers now fiancé then I’d seriously reconsider my partner choice because you clearly want marriage and he doesn’t. You will forever be jealous of her because she has a nice life. It’s unfair to resent her because she got pregnant so easily (I fully understand the heartbreak when trying for a baby and it doesn’t happen).

I can’t help but feel like she gets everything handed to her on a plate, everything I’ve been denied.

Why just her? Her partner got given a sum of money by his parents, he also owns the house, he’s also travelling and having a nice life yet all your upset/anger/jealousy is with her

Exactly this.

Switch off your social media and focus on your own life and goals.

At your age I hadn't even met my husband, the father of my children, the man who has treated me better than any boyfriend ever did before.

Get rid - and live your own life, make it whatever you want it to be!

he’s called me a miserable bitch and bitter

Your partner is the one you should have a problem with, I would never have a child with a man who said those words to me…..raise your standards,

Go out there and earn your own money and stop expecting to have it handed to you on a plate.

Start your own business. Upskill and get a better job. Take some pride in your own achievements in life rather than expecting others to drop them in your lap.

If it’s about money, set your mind to it, make a plan, knuckle down, make smart choices and you could be raking it by 30 without needing a man to provide it for you.

you're 22, dump this man and get yourself to the club

You would be foolish to have children with a man who has made it clear he won't marry you.

You are 22, you should be out having fun not settling down with someone with a low opinion of you.

I would dump your partner and remove yourself from this entire scenario. Its not good for your mental health. Comparison is the worst thing. There are always people better or worse off and thats just life. But you seem to want the impossible for you with a man that can never give you what you want. You will always be resentful and unhappy if you stay with him. The engagement party is distracting you from your real issue of not being happy with the man, career and lifestyle you have chosen. Only you have the power to change this for yourself.

This. Your partner sounds like a dick. She also sounds like a dick. You don’t need that shit, live a little and find nicer people. You are so young!!

Forget about her.
Focus on that loser you are with who calls you abusive names.
Keep your money and dumb his ass.
TTC with him is a HUGE mistake.

I can understand your feelings of jealousy and can imagine feeling similarly in your shoes but jealousy will only hurt you in the end, so you should try to work on it rather than dwelling on it. Your boyfriend is being insensitive and I wonder if he’s still the right one for you? Maybe you’ve outgrown each other? Your teens and twenties can be a big time of change and it sounds like your life goals don’t match up. You need a serious conversation about that the future looks like for you both.

Have you had any counselling for the fertility issues? That’s hard news to receive at any age, nevermind your early twenties. IVF can be challenging for any couple and having a supportive partner is priceless. I’d query whether he’s the one to be on that journey with. Choosing the father of your child is one of the most important decisions you’ll ever make, try not to let broodiness get in the way of choosing wisely.

What do you mean he “doesn’t believe in marriage?”. Marriage is a legal contract that protects you all. Don’t have a baby with him if he isn’t committed

Yep you have a partner problem and all this is doing is putting a magnifying glass on this

you are 22 far too young to be feeling this get yourself free now

First, do not waste any more of your life on this man. I wonder if you've stuck by him because you are desperate to have a baby and desperate to have a baby ASAP and - he's available. That sounds terrible but what I am trying to convey is that this particular man is considerably less important to you than having a baby, isn't he?

"my partner says he doesn’t believe in marriage even though he loves me"
Well I don't believe in unicorns, but the difference is that marriage exists and unicorns don't. So stripped of 'belief' he is saying he just plain old doesn't want to get married, ever. Why are you willing to put yourself and your potential child(ren) at the mercy of a man who won't commit to you (and them)? Marriage is more than a piece of paper, more than a wedding; it is a binding contract which offers financial protection to the party who may not be able to earn through paid work - say, someone who is growing, birthing and raising children.

Second, you're only 22, why are you in such a hurry? Seriously, why? And how do you know, at this young age, that you have a "fertility condition" that "will only get worse"? What are we talking about here, endometriosis? Or what?

If fact, everyone here seems determined to have children at a very young age. Is it cultural, do you come from a culture where you must 'prove' your fertility ASAP or be considered some sort of outcast?

Jealousy is a horrible,ugly emotion which will never make anything different. So yes - you are being miserable and bitter - he's not wrong there. But he was very wrong to call you a miserable bitch. FFS, stop the IVF nonsense, kick him into touch - go out in the world and live your life for you. Not having a baby is not the end of the world but right now you are on course to waste the best years of your life.

It's very clear that your anger and resentment isn't about her, it's about the fact you and your partner want different things.

Your anger is directed at her but really you're just upset that your partner doesn't believe in marriage.

"everything I’ve been denied" - you haven't been DENIED anything. Some people are fortunate to come from a background where parents can help with a house deposit but many aren't - you haven't been denied this.

Most of it is down to your choices, like your choice to be with a partner who won't commit to marriage and your choice not to pursue a lucrative and flexible career like the one you're jealous of. These things are within your hands to change your situation, especially at such a young age as you are.

Yikes! They’ve had £40k gifted to them. Other than that, they both work hard, earn well and have flexible employment. If that’s what you want, go and get it. At 22 you can do literally anything. If you want that life, work out how to make it happen for you, rather than focusing on what other people do or do not have.
And to be fair to your boyfriend, I do think you are being miserable and bitchy about it.

No she doesn’t sound nice and no she shouldn’t be lording anything over you, but your resentment is eating you up, and that’s not healthy or attractive.

Why are you with someone who doesn’t want to marry you. That’s just going to continue to be sole destroying if marriage is very important to you.

Stop focusing on her and do what makes YOU happy. Who gives a duck if it’s not in Bali.

Is she jealous of you? People (in this case her) that put people down are often jealous or insecure about something.

Personally I would go, make myself look a million dollars, ignore her, and really try to enjoy myself. Nobody needs to know what you’re really thinking in your head!

Now stop thinking about her and try concentrating on yourself. I know it’s hard, but fuck those that fuck you 💐

I’m surprised at the advice given to OP to find a rich man, I thought MN was all about being independent women. 🤔
