AIBU wanting to get married

[LifeAsWeKnowIt]

Hello,
I am new here and this is my first post.
So basically I am 21 and my boyfriend is 24, we've been together 4 years and we have two kids and a dog.
Things haven't been the best as we are catching up on finances after he was jobless for a month and a half. He now earns a really good wage and we are on top of things.

4 years ago I was a size 8. After two kids and being severely depressed I turned to comfort eating so I'm now a size 18. We don't have sex anymore and I'm sure it's because of this, but the love is still there.

I want to marry him but he's always said maybe due to the costs involved.
I'm not interested in a big wedding. I would be happy to go to the town hall and do it. I mentioned it to him tonight and again I got a maybe and he tried to change the conversation and got really shitty with me. He will never give me a yes or a no, should I just give up hope? Will he ever want to marry me?
Oh and I should add his parents aren't married and they've been together since they were 17. Might be where he gets his tunnel vision from.

Aww OP.

Definitely work on yourself first then you can enter your marriage feeling good about everything.

I think you have a good relationship, the sex thing bothered me in your first post but then you explained why. I'm sorry that happened to you.

Take your time and iron out those issues and then you'll have a good foot holding for your marriage.

I'm getting married soon (married before) I'm 44 but learnt through mistakes what marriage means. We didn't have to and at the beginning weren't going to but as our relationship developed (and we have been through the mill getting this far -against the odds type of thing) it now means a hell of a lot to both of us. We're getting married purely for love and commitment to our relationship.
