How do i get over this ex?

Welcome to "the one that got away".

I suspect it's a form of obsession. You had this vision of your future. You decided he was the optimal way to get to that future. It didn't happen, you were replaced quickly, and it all feels horribly unfair. You tied your ego to this vision of the future.

And so, being replaced, particularly quickly, is doing more than saddening you. It may also be messing with your sense of self.

I think that taking charge of your life (even more) is key.

You have been on dates, and that's helpful. But are you giving these guys a chance, or are you (consciously or not) comparing them to this guy?

If that's the case, then going on dates right now is meaningless.

So, my suggestion is to do things that will enhance your life as a person and bolster your ego and self-esteem.

Go out with friends. Take a class. Volunteer. Make art. Embrace fitness, and try something new.

In any and all of these areas, try something new.

Give your ego a kick upstairs with activities that have nothing to do with the quest for a mate.

If you want to date now, fine. Just be fair and open minded and keep it casual for now. This is for fun, not to measure a guy for a wedding suit.

Give yourself a good 6 months of this. And whenever you think of him, tell yourself he's missing out on all the amazing things you are doing. And then set aside anymore thoughts about him.

As in, you're doing whatever, he crosses your mind, you think-- ha, Bruce (or whatever his name is) isn't bungee jumping with Lithuanian spies. He is totally missing out! And then go back to your new Lithuanian espionage agent pals and bungee jump to your heart's content--- or whatever you end up doing. Eventually, any thoughts of him will become intrusive, like a gnat to swat. And, they should be.

Because whatever you'll do (bungee jumping or whatever) isn't to make him jealous. It's for you to have fun or learn something or help others.

Live your life without obsessing over him. You are a fine and worthwhile person and he is the one who is missing out.

If none of this works (like I said, give it a good half a year), then seriously consider therapy.

You are worth more than this.

Thank you jespah for the wonderful reply, you captured it right. I went on many dates but i gave a chance to this one guy who has been dating me for 10 months, supposedly we’re friends right now because he told me he doesn’t want anything serious. That’s where my comparing starts, my ex has a better relationship than me, he’s so in love and etc.
As you said i should keep reminding myself on the things he’s missing out from me.

Sending Love <3

The reality it still hurts is because you have a bond with somebody. Maybe you and the person could just be casual friends and sleep around once in a while and not be a "couple".

Dating is not the same as being married. The Date does not count as a relationship. Even if somebody is sleeping at your place the dating does not matter. When your "Going out" it does not matter. Even if you introduce somebody to your family. Dating is just dating.

I say the above only because various religions, race, and cultures consider this to be true. The problem is that dependent on the culture you have to understand the robotic society of being inside a liberal nation oppose the robotic society of a Traditionalist nation.

You have people who see other nations as a place to let off a few gametes and not care if they are the parent to get an abortion because they see children of that nation not to be of any real importance at all or real.

Dating does not count. Again you could be friends after whatever and do non sexual things.
