Ex- boyfriend

It really depends. Why did you and your ex end and why are you and your current boyfriend together? If you don't feel fateful to your boyfriend then maybe you shouldn't stay with him, yet that doesn't mean getting back with your ex either. From the sound of it he is jealous of your new relationship and I'm not sure that your relationship would last very long once you were his again. Besides that, why are you with the guy you are with now. Wait it out a bit before making a quick decision that you might regret later.

What's the reason you dumped him in the 1st place? Ask yourself if for that reason, has he changed. It could be your only lusting your ex, if that's the case, its not worth it if your have a really good guy now.

Whatever you do don't break up with your boyfriend for your ex! Biggest mistake trust me. I did that before and my ex was just messing with me so I could break up with my boyfriend. See if your ex flirts with other girls if he does then he's probably messing with you. Also if you still like your ex then it's not fair for your current boyfriend.

Your ex is your ex for a reason. You or He didn't just wake up one day and think oh I might just break up with them today. One of you did something extremely wrong to the other. Your current boyfriend is there because you are good together. Just because you ex turns you on, doesn't mean your gonna be happy with him or that he even wants to be in a relationship with you. You gotta think about this more wisely.
