ladies I need your help!

I get induced Tuesday (jan 12th) with my first baby and im so darn excited but heres the thing, I received messages from another female today in regards to my bf and his doings and in some ways im so hurt! I brung them to his attention and he seemed pretty concerned but not surprised! We have been together 4 years and even talked about kids so the baby isn’t the problem! (at least I hope not) with words he has been there for me but action wise i am slightly disappointed. i expected more from his end and idk if its just the hormones or im really just fed up atp, but I want and need a mental break from this “relationship” my mind is all over the place and I never wanna take from my child when it comes to his well being no matter the history of anything! Im stuck on how to tell him that I need a mental break from the relationship and just want to focus on being parents for a while and revisit the relationship talk later. My child means everything to me and i feel my postpartum kicking in quite quickly now and just the thought that he may or may not was entertaining another female makes me cringe. nov of 2020 I lost my dad, my relationship with my dad side of the family crumbled then being insecure about the pregnancy weight gain and the way I looked half of the time Just all put a big burden on me and all im looking forward to is being a mom bc growing up i never had anything consistent or stable 😣 help me out ladies! how should I go about this?
