I need to know if I’m in the wrong

So me and my boyfriend have been off and on again for 8 years now and I know it’s a long time but to the topic. Me and him broke up last year due to stupidity decisions but in the process he got someone pregnant and he didn’t want to be with her but he came back to me...Ik ik you thinking why in the hell did I take him back i truly love him and im welling to work on our relationship...so we been back together since October and I have my some doubt about is relationship with his baby mother...cause he telling me that he just co-parenting with her...but I don’t understand why we keeping our relationship a secret (over other bs but I feel like he only doing it for her feelings ) and when we have sex...he cleaning himself cause he don’t want to smell like rubbers(I’m not on birth control at the moment) I said something today cause I felt some type of way cause why every time why every time you go see you son you have clean up before you go over there😒😒😒 I know this baby only 2 months and I have a long road of head of me...but he got mad at me for saying something to him...cause the only reason I said something cause he been with me

All day but I been sleep and not feeling well and when I wake up you want to have sex then leave i got mad cause why you do me like that...taking about i been waiting on you to wake up so you can go get your car all day so I could see my son...I was like why didn’t you go while I was sleep...you have a key to my house...I could have waited on him to came back...but he got mad at me...so question am i in the wrong for speaking my mind
