Partner keeps us a Secret and no one knows

Hey there! I am a 30(MTF) and my Partner is a 31(M). I have been with my Man for basically 5 months now and not one person on his end knows about me, about us! Each time I bring it up, with what he says, it’s clear it is because of his past relationships and his 2 little kids that he gets every other weekend and he wants to be sure with me. The thing though is, we actually live together and have been living together for over a month now. Not 1 friend of his knows I exist. His kids doesn’t know I exist (he has been making me stay at a friend’s house when he has them). His family doesn’t know I exist. His Parents doesn’t know I exist. No one knows I exist. Some weekends he takes his kids to his Parents’ Trailer for the weekend and again no one knows I exist. He told me to move in because I was having some housing issues and almost had to make the decision to move back to the City I am originally from. A few times he tried to bring up referring me as a Roommate just for now (which I shot down). Our sex life has changed too. His romantic side due to the past I have not seen yet. I feel like I am paying the price of and for the ones who have hurt him before. I’m always working and he just quit his job out of dissatisfaction but he was just hired. Now he’s back to being unemployed. On my end, people know he exists and what he is to me. I know I do love him greatly and I care about him and us however if this continues next month when we are 6 months in I may have to make a hard decision. I don’t want to spend another 6 months like this and I don’t deserve it.

TL;DR, Been with Partner for 5 months. I am a secret on his end. I am struggling with it. Next month during month 6 if it continues, I may have to make a hard decision.
