your BF is not willing to contribute money into the relationship. It's better to keep dating and make sure both are ready to commit. After you get engaged, then move togather. Either buy a house together or he needs to put the same amount of money you have in the house.
When we got engaged, my LG sold his house and moved to mine, because I don't want to get a new job and move to his city, so he moved to my place, get a new job and also put the money into my housse. We also changed the title so the house belongs to us both because we have equal contribution. I like be fair to both.
