Should i contact my ex via twitter? iin?

Leave the poor girl alone. From your very confusing post, you left her, right?
So she probably didn't appreciate it and she really won't appreciate that you're in a relationship with someone else now.
Unless you WANT to hurt her?

It's normal enough to want to talk to her, whether over twitter or whatever. However, it is wise not to do it. You've got a girlfriend, and getting in touch with the old one can just lead needlessly to trouble. When you're unattached, then perhaps you can get in touch.

Followbackers are lame. Follow me! I promise I'll follow you! Lame.

If you'd feel bad contacting her, doesn't it suggest you're doing something wrong, or perceived as wrong?

I think you should tentatively explain to your current girlfriend that you'd like to reconnect with your ex, to see how she's doing, but that there is no ulterior motive or remaining romantic feelings - and that if she wants she's welcome to see any tweets between the two of you, since it's an entirely platonic deal. See what she thinks.

However, if it ISN'T entirely platonic, and you do have residual feels for the girl, then it's a bad idea to reconnect with your ex whilst you are in a relationship.

You're an asshole.

It's normal. But you shouldn't do it. Leave the past in the past and focus on the present, if not for yourself, then for your ex girlfriend, or better, your current girlfriend.

Dont do it.. if you miss the experience with your ex let me tell you something... when u think back of a moment your brain will trick you and make that experience so much nicer than what it actuallly was, stick with your current girl and dont be a dumbass !

After all u cant turn off feelings after caring avout someone for so long !

If you are going to talk to her at least be classy and send a letter or call her. Do I think you should contact her? No, I don't.

"Is it normal that I want to talk to my ex?"

Rather depends why, doesn't it?

Worried your present gf will 'find out'? And 'you wouldn't want her to do the same....'

Examine your feelings. You should not contact number one without telling number two really, I reckon. You say after the fact that you loved the first. Do you feel differently about the second?

I wish you well.

I was in this situation before if you two (you and your ex) were a very close couple like me and my ex were ... I wanted him to get in touch just to be able to catch up and find out how he was gettin on etc .. But yes if you care about her still you should but do.not keep it.from your present partner as it will hurt her I made that mistake when I waited ao long instead I.contacted him by fb and my partner found out at the time I taught a harmless 5 min convo no harm be dobe but turned out he didnt feel like I could talk to him about it and we ended up having a massive fight and broke up we are back together now and my ex and him act get on well were all a group of friends ... Explain.to.your gf that u just want to catch up and see how things are going tell her she could come along if would help go for coffee/tea if ur ex has a partner bring them along to it worked for me !
