OH...the pain you're in...i feel it.
Please please run. Please run.
After 2 years, you know if you"re ready or not.
Life is too short!! I'm not going to say anything mean or negative about your partner. He has been honest and stated that he doesn't feel ready and doesn't want to marry. He is also had time to think about it. And still feels the same.
I completely feel your pain when it's burst out of you with the proposal. And I suspect you hoped he changed his mind Or had tad time to think about it? And reveal his true feelings.The thing is he has revealed his true feelings, and he said he isn't into marriage or ready for marriage etc etc. It's going to hurt. It's going to feel probably something along the lines of having your heart ripped out and there will be times where it will feel lonely, and you will question yourself over and over, wondering why you didn't just keep your mouth shut and not ask him!!
Howecer
However, im glad u did!! You've done nothing wrong in my opinion. Haven't read any of the other replies. Well, 1 or 2, but not most of them, and I imagine that you'll get some people replying to you telling you that you did the wrong thing or even telling you off a bit. That's gonna hurt but big girl pants on!! Do lots to boost your confidence.
Cry, eat well, drink loads of water. Get loads of vitamins, sing get exercising.Whatever it is, you need. Spend time with friends and vent. Give yourself some space and allow yourself time to heal. I say this from personal experience from other girly friends who've had this happen to them. (Both of which went on to find happy and fulfilling marriages after a few rocky years) One friend found out at thirty five that her partner didn't want to ever marry and she spent the next five years travelling and had the time of her life. She met somebody in australia and emigrated!
Incidentally her former partner lives in a two up two down in a dodgy area, is unemployed spending most of his day sitting on the sofa drinking energy drinks. I see him round town pushing a pram looking bloated and low. Its really sad to see actually as he isnt a nasty man...just directionless.
I loved my last partner and was heart broken to leave him. I doubted my decision for years. He wasnt ready for marriage or what i felt was proper commitment. I thought my heart would never heal and it took a few years but now i feel very little other than slight pity and a funny feeling that i escaped something that would have squashed me.
He is 60 now and never married at all. Lives alone, never had another partner.
Id have felt more comfprtable if he had moved on and found new love. He isnt a nasty person..just a lost soul with debilitating depression that he now doesnt manage at all. I realised that it wasnt my "fault" or my defecit.
He cant love anyone as he isnt well and doesnt love or value himself. I tried to help when i first left as he let himself go so badly.
I moved on to find the love of my life and you will too.
Dont wait wondering about what ifs. You will never fully settle into this relationship in the way you deserve. If he does change his mind you'll always wonder if he married you just to placate you. That thought will always find a way to erupt and it"ll erode you. dont sit at 60 or 70 wondering where your 50's hsve disaappeared to.
Good luck.
