Should I tell him?

If you are only talking to your ex as a friend and there is nothing going on you should have no reason to keep it from your current boyfriend. But you have to be ready to possibly make a decision between the two because I doubt your boyfriend will be comfortable with it. For example, I am a very comfortable and secure guy and don't ever get jealous but there is only one thing in the world that I can't compete with and that is History. You and your ex have a history and that can be very scary to a lot of people.

I would tell your boyfriend and just reassure him in every way possible, Keeping a secret and having it come out later will cause a lot more heart ache from all angles.

yeah you should tell him, but he is not going to be happy at all. He is going to think he is not good enough for you and that you still want your ex back. Then he will stop seeing you and then your ex doesn't want any part of you then you are with no one. Because right now you have a boyfriend and that is what should matter now not what happened in the past that is behind you now you future is with your boyfriend now not your ex. so tell him that you are talking to your ex and get it over with and stop talking to your ex so you don't lose your boyfriend because if my girlfriend was doing that I would be really upset to let you know and would be really mad. So tell him and hopefully he forgives you for what you have done to him. So kiss up girl!

always tell him.keeping secrets will ruin the relationship you are in now. he may not like the fact that you are talking to him but he will respect you for being honest and up front.

you should tell your boyfriend because if you don't he will think something is going on!if you tell him at least you know your being honest with him.if you don't tell him you'll just make things worse just really depends on why your talkin to him and what about?

well if you tell him you would make him paranoid about you cause he be wondering "is she cheatin on me" what is she doing with him" there more likely the words that be rambling inside his head do not tell him until it's they right time because you and ur ex could fall apart as friends and if you tell ur lover before hand he could break up with ya and let you alone so wait and see what will happen ok best of luck

I don't see a reason for you not to.
So what.if ur talking to ur ex.its not actually a thing ur not supposed to do if ur in a relationship you know.
i think that you should tell him but just keep it to talking with the ex you know.let it not get in to something serious.

yeah you should tell him but why would you still be talking to your ex?when you already have a boyfriend how ridiculous is that? That's when problems start the point of ex means old boyfriend not friend and old boyfriend which means once its over its over

I think in a relationship, it's very important to be honest. Even if you were talking to your ex, you weren't talking into getting back with him right? As long as you guys are friends, I think your boyfriend wouldn't mind you talking to him about random things. But, if there are some things going on between you and your ex, you might not want to tell him.
