I've just come out of a on off 3.5 year relationship where I know looking back I was treated very poorly. It was a push pull negative cycle situation and my ex had huge disorganised avoidant attachment tendencies. Wed manage 6-9 months at a time. We'd get close he'd push away, the relationship would end and then we'd start again once he'd calmed down. During these breaks I'd get on with my life, be incredibly upset but keep my hopeful we'd work it out. During the breaks he'd seek out casual sex and flirtations to keep himself feeling good. He is a known flirt and locally seems to have had sex with every third woman. I have only just accepted this despite knowing about various things over the years I always gave him an excuse. The last time when he thought I was moving on without him he went all out with talk of marriage, buying a home together, booked us a holiday etc but it's happened again where he's told me that he knows now there's no future and it's not going to work. Fair enough. It's not. For background, my relationship with the ex before him lasted 10 years and we have two children together. He's emotionally and verbally abusive to me still. I don't listen to him but occasionally it gets on top of me as it's just none stop.
A few friends have spoken to me and said that they realise my self worth is incredibly low and I'll be honest it's not something I really understand. My friends tell me I'm funny, kind, honest, dependable, attractive and a real catch but have no self worth.
I scrub up ok, wear nice clothes on a toned slim body (I know it's not everything just setting the scene) have a good hair and know what clothes suit me. So to look at, it's all ok and don't have any body hang ups.
I have a good strong group of friends to I can rely on but my closest friends and family live over 250 miles away so I can't just walk down the road to see them that frequently.
I can overthink things and I do have imposter syndrome at work but that's also partly down to these relationships taking over my head and neglecting some of the work I need to do.
I know I've allowed both of these men to treat me appallingly, time after time and I don't know why I've allowed it or how to make sure it doesn't happen again.
So what is self worth and what is the route to building it up and making sure I don't accept this again. I feel confused and lost.
