<human>: Can you summarize the given text in a few sentences?

My husband and I have been married for 5 1/2 years. We have 2 kids, a four year old and a 1 1/2 year old. For the past year we've been having issues because after my 2nd child I bled for the entire year and we were unable to have sex regularly...or even semi-regularly. 

I finally stopped bleeding and we started having sex again. However, my husband would always have to initiate because I'm the only one working in our household and when I got home I would be tired and not feeling like initiating anything. Also, he watches the kids all day and he goes to bed extremely late, so when he came into bed and 4 am I was dead asleep and didn't feel like waking up, doing it, cleaning up, and then going back to sleep. 

So he sent me an email (cuz we both avoid confrontation if we can help it) to me about how he felt about our sex life or lack thereof. I told him that I understood but for the past 2 years I'd been working over full time, been pregnant, and then been bleeding so I was just overtired and needed some time to get to 100%. But I did make an effort to be more...willing I guess? That's not the right word but w/e.

So anyways, I thought things were going good but now I found out he's been using kik to message people and that he has a profile on matchedup or something like that. I don't believe that he's actually cheated on me because honestly, he doesn't have any free time to do it. He's with our kids 24/7. I mean, occasionally I take them out and I suppose he could cheat then but I doubt it. And I found out about this after seeing notifications on his phone from people I didn't recognize...obviously he doesn't know that I'm digging around on his phone.

However, I am NOT ok with the fact that he went behind my back and onto that kind of site to begin with. I just don't know what to do. I  have to confront him about it but how? I need help.
<bot>: My unsatisfied husband made a profile on a hook up site but hasn't cheated yet and I don't know how to bring it up.
