About a week ago, I finally broke it off with a girl I had been seriously dating since high school. We had been in a fairly mismatched, unhappy relationship for sometime, and I believe it was better for both of us to break up. I am now happily single and haven't missed my ex very much, if at all. 

So why am I crushed at the thought of her meeting someone else?

I haven't really thought seriously about her since the break up, and I deleted/blocked her on all social media and my phone for a quicker healing process. I had been growing more and more distant from her until finally breaking off our relationship, so I think that explains how nonchalantly I have been handling the lack of contact. But the thought of her meeting another guy, and becoming romantic/sexual with him makes my blood boil. Also, I am deeply hurt by the thought of her drinking/going to bars now, since I am a teetotaler and she kept alcoholic intake to a minimum during our relationship. 

Please help me to overcome my irrational jealousy and heartache at the thought of her putting herself back out there. I am obviously trying to do the same thing, so why am I so irrational about her doing it, too?

I broke up with my girlfriend of 4 years, but am still upset with the thought of her dating again. How do I overcome this irrational jealousy and heartache?

I am a jealous, heartbroken, and hurt ex-girlfriend, who feels like she was cheated on by an ex-boyfriend. I want her to be happy again, but I also want to make no apologies for the way I feel about her dating again.
