Most Helpful Guy
It's not on you to save it. He has insecurity issues and he need to think about what he really wants. I think him asking you to get married while he has these issues is a big mistake and a red flag. You need to tell him what you want in the relationship and he needs to tell you what he wants. See if you can compromise on the major issues or what are deal breakers. If not you might need to postpone or possibly call off the engagement.
