Am I Overthinking or Is My Bf CHEATING ?!?🤔

Kirah
So to make a long story short.. Me & My bf been together for almost 8yrs now (been together since high school 2009). We're each other first love, like we're crazy about each other. We just had a baby in October 2015, but before I got pregnant our sex life was POPPIN' lol he couldn't keep his hands off me. When I was pregnant with our son he told me as I grew bigger he didn't want to have sex with me bcuz he was scared to hurt the baby & etc. So I didn't want to force him to.... Now that I'm not pregnant anymore, it seems like he still doesn't want to have sex. Is he cheating or am I buggn' ?? I need answers !!Â
