Husband and porn..

Lady’s I recently found my husband has been watching porn a lot I’ve been together for 12 years and the last year our sex life hasn’t been the greatest but the last few months we been trying to conceive for a second child I thought our sex life was getting better and more often I was more Into it idk if it’s because I’m getting my sex drive back or what but we been doing good and from what I noticed I thought I was pleasing him just fine I’m way more open then I’ve ever been. Is it wrong of me to be turned off by this and he’s doing it in our basement when he gets home from work “man cave” and I’m home and our son who is 7 and in the evening in the basement I guess when he says he’s playing games he’s lying . I don’t even no what to do or say or even feel I’m hurt I know it’s not cheating and most guys do it but I thought we were in a better place. And I literally have no gf to talk to about this.. it makes it even harder
