Feel Like He Cheating

Sherita
Hello ladies for everyone who don't know me my name is Sherita and I'm kind of new here. But by husband and I have been together 7 in a half years. I'm 26 he is 36 when we first met we was friends didn't see a relationship coming I was with someone else. We have had our problem over time but nothing we didn't work out. So here I am pregnant with our third child (24 weeks) and for the last week I have been having a feeling like he is cheating on me. I'm a plus size women so I'm trying not to gain much weight which I haven't but I still can't look myself in the mirror without feeling some type of way. Right as I was starting my weight lose journey I found out I was pregnant. Things are so stressful right now. We only have one income due to me being high risk and can't work. I been looking for real work from home jobs haven't had any luck other than that I'm home with the kids all day. We live with my mom for the time being one of those things where in Mississippi the cost of living is high so need both incomes but that's another story for another day. Last time this happened he was talking to other women but didn't sleep with anyone else. I feel so alone half of the time and we can be in the same room. He playing his game and I'm doing school work. I'm a full time student. I just don't know what to do anymore looking for advice please
