Is it normal for my current boyfriend to always hangout and be with my ex boyfriend?

Normal? Uh, no. A problem? Well, maybe, maybe not. Best place to start is with yourself. How do you feel about this? Does it cause upset, anger, confusion? Does it negatively affect your current relationship? You are the common link here, best to figure out where you stand first. :-)

Now that you mention it, my boyfriend at the time (someone I still deal with-complicated) claimed to not like my ex boyfriend(someone I haven't seen or heard from since the breakup years ago) . Actually they both claimed not to like each other and one day my boyfriend called me on his phone because at the time he didn't have a way to get in touch with me. I was confused because to my understanding they didn't like each other. . They acted like they hated each other and I will never know why. Maybe he was just being nice to him anyway, Enough about me. I find it rather odd for your current boyfriend to be associating with your ex boyfriend period. I would be very cautious and I wouldn't trust it. There is no telling what they could be talking about in regards to you. Be careful.

No, I do not think it's appropriate for a current boyfriend to hang out with your ex because it would be hard to move forward.

I've never tried to pick and choose any of my partners friends. It could be that your current boyfriend feels close to your ex because they have you in common. If your current boyfriend is mature enough to see you for how you treat him and what then two of you have, and there is a strong mutual trust, then the ex shouldn't be an issue. I wouldn't necessarily say that it's abnormal, but personally I would be careful because things could get stirred up later if the relationship starts to deteriorate.

I would't say it's normal, but obscure. In some cases they are probably getting information about you more than anyhthing and to do that they get the number 1 source.

Maybe he does not mean anything to him but if you feel awkward with it. Then it would be good to talk to him about it. Using "I feel that..." or "It makes me feel... because..."

It's not normal, no, but at least they get along and he doesn't seem to have any bad feelings towards your ex.

It's weird but not entirely abnormal, if you feel uncomfortable you could talk to your boyfriend and let him know that you feel this way.

As long as your ex-boyfriend (if he ever talks about you) talks about you respectfully, and as long as your current boyfriend dismisses anything negative your ex says, there really is no problem. It can be a little awkward if the three of you hang out together, but if everyone is respectful then it is a sign of a healthy relationship and a healthy breakup.

It may be normal if they are friends before you and your current boyfriend are together. If not, I think its rather healthy that this happens because usually current and ex partners don't get along well. It's kinda hard because it creates a limited space for you, if you're with your ex he gets mad but with your situations it may not likely to happen. Maybe he's trying to know about you more from your ex :)
