Yes, EX’s do come back. It could be weeks, months or years later. It's rare that they don’t come back at all. 

Why do they come back? I think it’s because deep down exes never really forget you, and if they were the ones who dumped you they really do live with that guilt for a long time before giving in to their conscience and trying to work it out/make it right.

I also think they realize later on that you really were their best option and they weren't mature enough to appreciate you. Two of my exes are case in point here, especially my last. She had bad experiences with guys for most of her life, but then she met a man like me who loved and accepted her more than she really understood, but then cut me off and didn't look back. At some point - if it hasn't happened already - she will look back and realize what a huge mistake she made.

Often the people who dump us really do take us for granted and have the ridiculous misconception that removing us from their lives - if we have been nothing but loving and giving to them - will be the solution to whatever unhappiness or inner turmoil they have. And it isn't. So they later on finally realize they should've never let you go, and sometimes it's too late for them if we've moved on for good and forever.

But always remember, even if you want to reconcile, even if you love them the most and you believe that YOU would still end up shouldering most of the relationship responsibility and that you would become the “relationship police” - checking in often, taking the temperature of the relationship, (‘is she happy now? Is she about to leave me again?” Can I feel safe now? Can I be happy NOW?”).

You'll always be insecure about the future. Is it worth it?

NO

*Because in the end, If you cannot realistically feel emotionally safe and secure with them even with effort on their end, then I’m sorry to say it’s just- too late.\*

They'll convince you that things are different/ better now and they had a "genuine" awakening, but always remember the painful track record you went through with your breakup.

I know that sucks to hear. Trust me, I know. But it’s worse to prolong the inevitable.

Saying “no thanks” to another try with your ex does not mean you’re being punitive to your ex. It means that you’re being healthy, realistic & fair to yourself.
