Feeling lost

So my fiancé & I have been together almost 2 years now & have been engaged for a year (as of yesterday). He’s cheated on me with his ex wife/ baby mama last year. We’ve been through a miscarriage & now I’m 20 weeks pregnant. I forgive him for what he did but the thought of it never goes away. I try to trust him again but every time he goes out with his club brothers (he’s in a biker club) he tells me one thing but does the opposite. Mainly just says he won’t be out late and ends up staying later than what he says. It’s little things but I absolutely hate being lied to. And he knows that. He doesn’t understand that just because you may not be cheating again, doesn’t mean you’re not breaking my trust cause I’m still being lied to.

I’m constantly having to tell him that I don’t need anything from him but the little things do matter. He wants me to make sandwiches for his lunch and give him money whenever he needs it or expects me to basically do everything around the house. But I get nothing in return. & yes, I do have a job. 2 technically. I work mom-thurs 8-6 as an optician & fridays I’m a waitress. He used to do little surprises for me in the beginning & now I get absolutely nothing. I love doing things for him because that’s my job. But not if I’m not getting anything back. Why do guys do that in the beginning and then once they have you, they stop. They still matter. Well anyways, yesterday I was on his Facebook and I saw he was messaging a friends ex girlfriend. He really didn’t say anything bad besides the fact he told her he’d be deleting their conversation later. But he didn’t stop her from what she was saying. She asked him when her future step child was going to be born” and he just answered with the due date. But to me he should’ve corrected her ass & that’s what upsets me. We talked about it and everything but I’m just still not over it. I messaged her too and then she ended up clocking both of us after I had asked all my questions. He says he understands why I’m upset but doesn’t understand that that’s not really respecting me because if it was an innocent conversation I wouldn’t have been mad and he wouldn’t have to delete the messages. Now I just feel like he’s cheating all over again or if I would’ve waited to see how far the conversation got, he would’ve ended up cheating with her. I feel drained, I feel worthless and I told him these are just warning signs. I keep saying I’m gunna leave but don’t cause everything gets fixed but I told him he’s gunna keep pushing and pushing me away and eventually I will be gone. And he said he doesn’t want that to happen, of course. I just want to be able to trust him again but I don’t know if I ever will be able to. 😪
