How to stop being so jealous?

I've had a few failed relationships this year and they have moved onto someone else, part of me wants them to be happy but then the other half is incredibly jealous. The last one I broke up with him and didn't want to be with him till I had heard he was seeing someone else, I know that he were to take me back it would last a couple of days till the novelty wore off and I remembered the reasons why we broke up in the first place.

Another instance where this has happened is with someone who I have had feelings for in the past (I don't anymore) and then when I see them commenting on someones wall or something (not that I Facebook stalk him but it appears on my newsfeed) I get jealous and start thinking ''who's she?!'' and ''why's he commenting on her wall?!''

I sound like a terrible person I know, how can I get over this?

Natural human reaction to want to be the best and/or most important person. Even if you don't want to go out with someone (anymore), it still doesn't stop you feeling inferior to the next person they choose to go out with, especially if they left you for them.

Just find something else to take your mind off it, weather it be another potential partner or other hobby.

Hmm okay thank you. I left him so I shouldn't care.

Not a good time to find a new partner yet but thanks for your help anyway

Just because you left him doesn't mean you're not subconsciously thinking "WTF! I'm a beast! How is he getting over me so quickly and already going out with some other sloot?!?!"

Will go away with time - trust!

It will pass eventually but it might take a little while.

Unfortunately I am exactly the same really and I used to think that feeling that way was wrong and I would try to push it away.

It's actually ok to feel jealous, it's perfectly normal. I found the more accepting I was of my feelings the less they stuck around and the quicker I seemed to get over it.

I find that as I've got older, I barely feel jealous anymore. I think it was partly because of one of my relationships: my Ex-GF was rather jealous & somewhat controlling. So after being on the receiving end, I thought there's no way I want to be like that to someone.

does it really matter? dont you have more important things to worry about

I don't get this in forums, people start a thread expecting serious answers and help/advice and then people say stuff like this... -_-

I didn't even see his post... oh well

Honestly, I'm same. But best thing to do, is to avoid them at all costs (social media and irl) . Being jealous means you may still have feelings for them somewhat.
