huge back story of on /off relationship. But I was totally single for 1 year and in that time built my self esteem from nothing to pretty high .learnt a lot about myself and learnt new skills. Then ex comes back on the scene and I surprise my self by taking him back . Things didn't work out and I'm back to zero confidence low self esteem and feeling depressed. I can't work my self out . I question why did I take him back when I was doing so well . I just need some guidence please
