Bf suggested that we move in with his parents

My boyfriend and I have decided to move in with each other. The plan was to move in without each other when my lease ended, he was suppose to move back in with parents and save some money while waiting for me.

My roommate and I signed a 6 month lease and planned on renewing it for another 6 month however, she let me know that she is considering moving in with her bf.

My bf suggested that we both movie with his parents to save up some money and buy a flat or at least save up some money to make buying easier.

I’m conflicted being that it’s a big risk but it will also benefit both of us. His parents are okey with the decision, they’re even making some changes to the house to make us feel comfortable.

But I keep thinking it’s a bit of a low life thing to move in with my bfs parents.

Any advice?
