[32f] my bf is [34m]. Have I fucked up too much?

We've been together for 5 years in June. I was coming out of a crazy marriage. One in which I went to couples therapy by myself, and was faithful. We had a daughter together. He lied, cheated and sold drugs. Our marriage was over before the divorce.

I met a guy around that same time. My current boyfriend. My ex husband was constantly telling me he wanted our family to reunite, and tbh, I haven't been single since I was 16. So, I slept with my ex, once. Broke up with my boyfriend, had a couple of one night stands, got back together, got alcohol and drug seduced (but doesn't matter, for all intents and purposes, I cheated) and the one night stands, were people he knew. Then we broke up and, my boss gave me the attention I craved, and also bought me copious amounts of alcohol. So we "dated" for like 2 months, and then I went back to my ex.

He tried seeing other people, I believe he slept with a couple of people.

We hardly have sex, because he says he wants to fall in love with me again... I try not to talk about it. I'm trying to give him his space.. But I suppose I'm trying to over compensate for all the wrong I did.

We fought today, about lack of sex.. But came home today and ravished me... I asked if he'd rather take some time apart, and he says no...

Am I crazy to think that, THIS, I'll be who I grow old with? Can a relationship come back from this? I'm clinging to the beginning... Before all my bullshit.

PS. I'm medicated, and albeit my sex drive is existent, it's not looking for any strange. In fact, making me wait, is kinda a turn on. I'm used to always getting my way sexually.

PSS please don't bash me... Men cheat all the time.

TL;DR cheated Multiple times, got back together with me, lacking sex life, can relationship work?
