I don't think this is a very healthy situation. If he met her while he was with you and has had dinner with her alone- yeah, I'd be worried. I would ask him how he'd feel if the roles were reversed.

I would encourage you get out of that relationship. What he is doing is not something a boyfriend does.

I've heard that "Just friends" thing before. You don't go out on a dinner date with another woman alone. He should have taken you with him. He is paying WAY too much attention to this other woman. He's not only disrespectful to your feelings, he's shallow, self-centered, and taking advantage of your trust. How many times are you going to sit there and wait while he goes out with his "friend"?

I think that if he told you all of this about his new friend, he's being honest with you and maybe there's nothing to worry about.

I'm not surprised your afraid, I would feel the same way and I'm sure MOST women would too. It sounds like a romantic date to me... dinner and a walk. The answers here are all saying the right thing... disrespectful etc and it's true it IS! But you know the details better than us. If I ask my boyfriend if he thinks a certain friend is attractive or not, he will and honestly..yes or no... but that doesn't mean HE is attracted to THEM! Also there are some situations where friends go out for food together in a non romantic kinda way... sometimes it IS just food... and some people like going for food as a way to socialize. I'm just trying to give a different perspective here but I have to be honest, I wouldn't like it one bit. I guess at the end of the day it's about trust. Do you trust them being just friends? Do you trust that although he may find her attractive, that he loves you and nothing will happen? The ONLY thing you can do is make it clear to him how this makes you feel and go from there! If he continues to go out alone for dinners and walks then he knows this will upset you and therefore not respecting your feelings. However... it's promising that he wants you to be friends with her too... and if you meet her and get to know her... you might feel better about the situation. If nothing good comes of this, then your only choice is to either move on or try and trust him... but I say keep friends close and enemies closer. If she sees how close you two are, she may start to back off! Here is hoping!
