Should I let him or Not ????

If you're uncomfortable with it, then say so. You should trust some of your gut feelings. But, tell him what you would be comfortable with. Tell him that you don't mind if the three of you going out, but that you don't feel like the need to be calling or texting or emailing or IMing. Those things can get really intimate. Tell him that's how you feel about it now, and that even though it may seem irrational you would regret telling him otherwise. Tell him that your feelings on the matter may change, but you may need some time. Let him know that you trust him, but he is such a great guy that you aren't sure if you can trust her yet.

if i was in your place i wouldnt let him. they were each other firsts for a lot of things, so theres feelings there and a special bond that neither of them will have with anyone else. he cared about her so much to do things with her, and the only reason they broke up was cuz she was too controlling- not because he didnt like her. its completly up to you if you allow them to be, you do trust him a lot which is good, as long as you know he wont do anything. but wouldnt it make you feel nervous just a little bit if the 2 of them were hanging out together while you were at home or somewhere else? what if they start hanging out a lot and he realizes he made a mistake, or if things go too far?

I wouldn't. Don't think of it as best friends, it goes deeper. Any relationship I've ever been in I was best friends with the guy I was with - I mean, you spend tons of time with them and really like them. At the time, I wanted to remain friends and thought that would be cool and wondered why more people didn't. In the end, I'm really thankful that I didn't, as I look back on it. Be honest and tell him you don't feel comfortable with it. Don't say you think he will cheat or that she will steal him, just say that "for now, I don't feel comfortable with it." and leave it at that.

Go with your gut instincts. Women can be vendictive when it comes to ex's. Why does he need to be her friend anyway, who cares if they shared alot of firsts. That's the past and that is where it should stay no matter. He's moved on, and he needs to continue to build and grow and have more firsts with you period. There is no way that it even makes logical sense that he should even need to be friends with her, unless he secretly has already been and just wants your ok to continue...Good Luck

I think you should follow ur feelings! If they're telling you that she is bad news then maybe u shouldnt let them b friends! She could possibly still want him and how do you know that their conversations are gonna stay "friendly"? They used to date afterall! If you trust ur man then let him have friends! Go and b friends wit one of your exs and see how he likes that! If he's not cool wit it then you have the answer!

i really dont think they should be friends, it makes u uncomfortable and he should understand that. im not saying that u should go now and ban all of his girl friends. but they do have a history and they have slept with each other.

if he gets mad at u, u really should take a look at that, he might still have feelings for her.

if he is as nice as u say he'll understand why would he want to risk his relationship

Allow him but you must also tell him the truth that you are not comfortable about it. Tell him that you do not want to be selfish and not understanding but you cannot just stop feeling bad about it. Tell him the truth but do not pick a fight. He should listen to you. If your feelings matter to him a lot, he will understand you.

No it's not bad it is natural to get jealous or over protective of whats yours. If you don't trust him then tell him no. If you trust him let him have friends.

Well if it were me I would let them be friends...but I don't think I would give them all that freedom to hang out alone and stuff. Tell him that if your his number one than he shouldn't mind if you become friends with her as well and that way you can hang out with both of them and know that there is really nothing going on between them.

If he say's "he only wants you", why isn't that enough fo you to understand? Obviously, you really believe him, which is why you shouldn't worry about a girl takin him from you. Just trust him, and don't worry about it so much.
