Tricky one. Think we've all been addicted to bad relationships on here, myself included.
Reading your story takes me back. Deep down I think you know this man doesn't love you. You're clingy because you're trying to cling onto something that's not there.
Actions speak louder than words. If he loved you he wouldn't cheat on you, he'd want to speak to you and call you, he'd want to spend all the time he can with you.
When you find this man you will feel right and happy.
Deep down you know this man will never be the man who makes you truly happy.
I understand how hard it is to walk away because you're addicted to the idea of it working.
At some point, when you have had enough you will walk away, and it'll be easier to do then.
You need to learn to stop calling him. Call him once, if he doesn't answer, he knows it's his turn to call you back.
If someone doesn't want to talk to you they won't. Calling 1, 10 or 20 times doesn't make any difference. It just annoys them, and hurts you because you're being ignored.
I know you want someone who talks to you everyday, but this man doesn't want to talk to you everyday. You need to accept that or find a man who does want to talk to you everyday.
This man will never treat you how you deserve to be treated. I hope you find the strength to leave soon and experience real love x
