I'm wondering what to do. I do like him, but don't want a brief fling. I'm looking for something more meaningful than that.
If you look for bad things, they are bound to happen.
I don't know if you have been on these forums too long or you have had some bad experiences that leads you to believe all men 10 yrs younger than you automatically are looking for a fling but if you are interested in him and want to pursue anything, you need to drop the negative attitude or you will end up with a short fling, the guy seeing your attitude and walking away.
Trust your intuition and stay in the moment. Don't use past baggage to cloud your judgment today. If you pay attention to reality and what is going on it will be obvious on what his intentions are. What do you have to lose? After a few weeks you see he just wants a fling so you learn how to better spot folks in the future and you may have some fun along the way. But if you block out all possibility you may never find out if he is a good catch. Life is risk, life is choice. Go for it, why not!
