Why can't I get my ex partner off my mind?

You can't get your ex partner off of you mind because you probably still love them and care about them a lot. I have been in your shoes before and it's not easy. The bad news is that you may not be able to ever get this person completely off of your mind. The good news is that you may be able to keep from thinking about them as much, but sometimes we can't control what/who we think about.

I gave so much of myself to this relationship and I never saw the signs of him cheating when I found out he left without a word...I don't know what it is that wanted to hear him say. Because I now realise he never loved me the same way I loved him....He moved in with the other woman immediately ....that hurts me so much...its 3months now and I still think about him. I don't want him back I want to move on but find it so hard.

Simply because you're not willing to. You want to stay stuck to the old memories; you still can't quite digest the fact that it's over. You're lacking self-belief to go out there and find another partner, and more importantly you're not making an effort to leave an old habit behind - the habit of being used to your ex-partner day in day out, being more or less dependent on him/her,

He/she played a massive and important role in your life, this is normal. You loved this person and cared for this person.

Usually when an ex partner is on your mind, there is usually something you miss about them romantically or physically.

something is special from ex partner which make a intense on our memory so we can not off our mind.when other person have same speciality then we recall our ex.

From experience, sometimes it takes time to get over a relationship. It is completely normal to think about your ex partner for a long time afterwards. Although, i cant answer directly why, this is completely normal part of getting over that ex.

You can't get your ex partner off your mind because you are still living in the past memories. The future is waiting for you. Go chase it!

I think its normal to think of your ex's. Because you once shared that bond of love for them and love can never be forgotten

Getting over a partner isn't quick or easy, it takes time and patience. It may seem like it will last forever but it won't.
