How long have u been togther for? youre engage but, dont rush your life. do things when both of you are ready and settled. dont settle then solve. ou said he is the only onein your life right now. He isn't I just have more hope for you than you think you have in being truly happy. Communication is important, if he can't talk about and gets mad, there is a damaging underlying issue for him and it effects you too I'm sorry I can't help and tell you what to do but a relationship needs mutual trust and honesty
