I think I am finding this post so frustrating as I'm in a similar situation to you op. Just a few years ahead of you. We are married and I'm nearly due with our first baby together.
I have 2 dcs already. He has 2 dcs. I don't work. I do get a small income because my eldest has special needs. He is the reason I gave up work.
My dh works all the hours for me and my dcs, as well as his own. And I honestly could love him anymore for it.
This morning he's gone off to work - to get a bit of extra cash for my sons birthday coming up. I told him he didn't have too or didn't need too but he's gone anyway. He's shattered.
Last night I took my dcs out - I asked him when he got in from work if he could hang the washing out. When I got in.....he hadn't done it. He was asleep on the sofa. I did get abit annoyed until I went in the dining room and saw the massive pile of paper work on the table. Lots of paper work = he's had a massively stressful week. Then I didn't feel annoyed. I looked at the state of his work clothes and they were filthy. Hes put them straight back on this morning and gone to work - even when he doesn't have too.
He didn't take any lunch with him so I'm going to make him a sandwich and take it up to him later. He will tell
me not too as I'm really struggling pregnancy wise now but I'll do it anyway. I don't have too but I like him to know that me and all the kids value him.
I never thought I'd find someone like him. I could write a list as long as my arm of the little things that piss me off....but at the end of the day, they don't matter. I know I frustrate him too. You've just got to let those things go.
However these little things seem to be really frustrating too so this is why I think you are just not compatible. You aren't able to let these annoying traits go. He really does get on your nerves....you can't marry someone you feel this way about.
You've had a little dig at him again because he can't paint. So what? My dh can't work the washing machine but there's a hell of a lot of things he can do that I can't.
I also take it that he has no dcs? This man is pretty amazing in my book....to be able to just take on a large family and start providing for them? After just 20 months of being with you?
I don't really know what you want or expect out of a relationship. But what your dp gives you sadly isn't enough. Defo hold back on the wedding. Don't get pregnant either. Work on sorting your head out and take it from there...
