I have a hunch he’s cheating.

My boyfriend of 9 years (10 next May) isn’t affectionate with me anymore. Hasn’t been in a couple years honestly.

I’m sweet and affectionate. He doesn’t cuddle me, hug me lovingly, I try to kiss him and he shuts down. I tell him I love him and he changes the subject. It’s so rare we have sex and when we do it’s... not like how it used to be.

We have two kids together. I’m a stay at home mom and idk what to do.

We had a convo last year about marriage and he said he prob doesn’t want to.... after years together, he tells me this?! Early on in our relationship he cheated but I forgave him. When I asked him why, he always just said he doesn’t know.
