I'm hoping someone will be able to talk to me and help me make a massive decision. I'm seriously considering leaving my partner, but unsure if my reasons are selfish. I'm worried that I'll ruin my son's life if I leave, and that is something I don't want to do.
I have been with my partner on/off for nearly 4 years and we have a 10 month old son together. We are both young parents (I am 19 and he is 22) and adapting to parenthood has been difficult for me. I had/have PND (saw GP again today and I am being referred to a psychiatrist). Our relationship has been far from perfect. There have been alot of trust issues for me due to my partner lying and hiding debt etc.
When we first met I was 16 and had alot of ishoos (childhood experiences, anxiety problems/depression, self harming daily, bulimia) and I dived right into the relationship very fast. It was a very typical teenage relationship, I was 'in lurve' and wanted to be perfect (skinnier, love his faults etc) for him. After 6 months I was referred to a psychiatrist due to these ishoos and should have realised there was a problem there and then in the relationship. But being a stubbern teenager I wanted to 'make it work' i.e. be the perfect little housewife
(yes i was still 16 at this time
).
He knew about my bulimia but did nothing/said nothing to help me and neither did his family (I went to live with them). I completely changed my looks just so I could be 'the perfect girlfriend'. I know now this was absolutly stupid but my young niave self thought this is what I had to do.
I found out that during the very early days of my relationship he slept with my best friend and this comletely destroyed any trust I had for him. I know I should have left him there and then - well I know that now
You get the jist of it? It was utter teenage shite basically. Fast forward a few years...
Now we have our son, we live in our rented flat and we set a date to be married this October I KNOW I KNOW. A few months ago I started really thinking about our whole relationship after he completely lost interest in sex with me. I tried to resolve the issue with no avail, but it really made me think about everything. He shows no emotion what-so-ever. When my PND was at its worse i could be hysterical infront of him and he wouldn't bat an eyelid. Even now he is the same. He says things to me that make me feel like a shit mother (doesn't help on top of PND) things like 'you have been in the bedroom for the last 30mins you don't spent enough time with DS' or 'It's your fault DS hurt himself you should have been watching him better' (yes, when I'm washing up all the dishes he has left to fester and he was the one in the room with him).
Also, his poor hygiene is really becoming a problem. (Before anyone asks he is definatly NOT depressed, his whole family are the same, it's just the way he was brought up). There is no nice way to put it -he stinks. I mean violently stinks of BO and bad breath. The smell has been that bad recently that people have said they can smell my partners breath on my son's clothes
and I physically could not lye in the same bed as him last night because the room just smelt rancid because of his breath - it actually smelt like poo -actual human shit. I have tried to get him to brush his teeth/ go to the dentist but he wont have any of it. His teeth are now brown and actually started the other day to snap in half and fall out. It's not very attractive and a real turn off as you can imagine. My family have actually said that when they walk into my flat the first thing they notice is the rancid smell
I spend all day cleaning and trying to make the smell go away but it wont because obviously my partner still smells.
Aside from his faults he is an amazing father - he really is. But when I think about it that is the only thing keeping us together, because he is a good dad to our son. I have been deeply unhappy in this relationship for a while now. I am older and wiser (I hope) and i'm starting to find myself and realising that I made myself grow up too fast. I realise that I made some stupid decisions and that I made my bed and now I have to lye in it - which is why i am questioning leaving him. I want the best for our son - he never asked to be born into this and he certainly doesnt deserve to grow up in an unhappy household. But what can i do?
I do love my partner - in the sence that he is the father of my son and I care for him deeply, but I no longer feel that I am in love with him. I love him but i'm not in love with him IYKWIM?
I've talked to my family about it and they asked how I would feel if we did split and he found another partner. Honestly, it would be weird and i'd probably feel a bit miffed but doesn't everyone?
Reading this back I sound like a right bitch don't I? 
I'm sorry it's so long I've tried to shorten it but got all the main points in I think.
I honestly don't know what to do. I just want our son to be happy.
