You’re confused because you’re in a different place in your life than your boyfriend is, so you have to use a little empathy to eliminate your confusion! 🙂
If your boyfriend is only 30, single, never married with kids, and is putting you up on Facebook with sweet comments about you to friends and relatives, then you need to assume that his night out with a work colleague on a work trip, was just that — a night out, and not necessarily a date. He needs to be able to live his life and feel free in order to give you a commitment. He may not necessarily see his night out on a work trip with a work colleague as anything more than what it was, and I think that after dating him only a month, and getting good feedback from him, you have to back off and assume the best.
Also, understand that a month of dating, for a single and never married 30 year old, is probably less of a commitment than it may seem to you who is 33, divorced and a single parent. There’s going to be a difference, not because of age so much, but because of life experience, and you’ll have to be patient because marrying for him is going to be a much bigger deal, never having done it, than it is for you, who’s done it already.
So, enjoy the dating, be aware, as you are and have been, and practice understanding what it must be like for him, so that you don’t jump to conclusions or push too hard in a way that sabotages the relationship.
