So, my boyfriend and I have been together for 4 1/2 years. We've never really had a huge fight before, but every time he brings up moving in together it brings on a fight. My parents are very traditional and do not approve of moving in together before marriage. Now, my sister did it and they eventually got over it. But, the main issue is he wants me to move in with him at his home where he lives with his parents. If I am going to move in with him, I want it to be us two only. He doesn't understand that because he says we will be saving up money. He recently told me that if I'm not going to, then we might as well break up now. Which really hurts, considering we have been together for so long. The past few weeks I have been getting more anxiety about it because my sister is getting married in January and I told him if anything, it would be after the wedding so we can get through the pre-wedding months without even more drama. But, as it gets closer and closer I am starting to doubt if I want to move in with his family. I don't want to break up because I love him with all I have.. But I do think it's unfair he is giving me this ultimatum.
