by his age men have finaly come to grips with the idea that they want marriage and family. what you need to do now is sit down with him and explain why u sometimes arent trusing, talk to your man woman all of u listen to this. Talk to us damnit we are not mind readers. explaion it to him he will understand. Second this is a new day, he is a new guys dont dwell on the past. Trust him until he gives you a reason not to trust him. going through life not trusting people is a terrible way to go. I have ben hurt alot, and i struggle with it too. Most importantly is dont make him think you are constantly comparing him to ex boyfriends u have had and dont make him think you are just waiting for him to mess up. Let out a little trust and see what happens. He sounds like a good guy, Withhold sex for a week, tell him your not feeling good, but just one week, if he makes the week withougt complaining then jump his bones a screw his head off the next week. BUt trust, trust is so important, If u can trust then u dont belong in a relationship, Period. u cant make beleive its one of those things that has to be there or it will fail. I wish u good luck and hope things work out for you
