Overreactingon

Hello ladies I need some input on a situation in my marriage.. my husband and I have been together 10 years, well recently we had a baby 8 weeks ago prior to that he wouldn't even touch me during my pregnancy which I can somewhat understand.but then I ended up with a sexually transmitted infection" somehow" the one time we did the deed ( I was 5 months preg) anyways let's fast-forward to today 8 weeks after our son is born..his new thing is he can't sleep with me because I'm not on birth control. remind you we went 4 years with the" pull out" method never seemed to bother him before pregnancy never happened. our son was planned but now he won't touch me at all I'm not sure what to do anymore.I'm tired of living like roommates he works third shift so I'm always with the kids I guess I'm just lost or maybe I'm overreacting? I just feel so unattractive and my self worth has went down hill so much.

Update: for those saying we both cheated wrong! And when I did confront him about the sti all I got from him was "whatever lauryn"
