Is this wrong ? What should I do ?

Emily 🤩

Hi okay so me and my fiancé have been a little rocky in the sex part of our relationship but in my opinion it is completely understandable that I do not want to do anything because we have a 2 month old baby that I take care of all day while he is at work then he comes home and wants to have sex but I’m usually tired or just not in the mood so it upsets him and he goes away. I’m only saying this as kind of a back story and it is what helps me not be so upset over what I’m about to say okay so on Sunday we went to get me a few outfits from the store . On Friday he rudely went through my phone although I have nothing to hide but found messages between me and my ex that happened when me and my fiancé were on a break so he let that ruin our entire night well I felt bad but then we got it together and he let it go but anyway on Sunday he went inside to take some clothes back and I decided to go through his phone well I found him liking girls pics with their butt out which I have already told him before I don’t like when he does that. I then found that he messaged a girl on Snapchat on Thursday but like one of the girls that post nudes on snap and will never answer lol . Well all he said was hey and she never answered but it makes me wonder what would have been said if she did answer. I love him more then anything and I have not told him I found this yet but I did send a screenshot of the message to myself and blocked her but every time I call him out for things he gets all sad and lays around until I forgive him so it’s not even worth it to me . I need him to know that I’m very hurt by this though but I don’t want us to argue or fight because he is all I have . I’m in such a hard place I don’t know what to do 😭😭😭 please help
