If a male friend brings up marriage how should I respond?

Put yourself in his shoe's for a second. Here you are thinking of yourself as a loner with a guy that fancy's himself as a loner. Then, the more time you spend with him you start getting these feelings for him that you didn't expect to ever have for someone. Now what do you do? How do you tell someone that you like them and you want to have something more with them when your unsure how they will respond? He obviously likes you but he's not sure what to do either. This seems like new ground for both of you. If your both loner's and you both like each other as friends then maybe you should consider talking to him. You might be surprised what happens as you both talk about the possiblities of having a relationship. With every relationship we have struggles whether there friends, dating, or marriage. It depends or how you deal with the problems that come your way. Are you going to sit doan and talk about them or are you going to run away? Good luck.
