Sounds like you have to get in touch with yourself and deal with your insecurities and not depend on some man to make you happy – I have always hopped into relationships and nurtured the man etc… boring and now I love being on my own , it’s great ! I think we automatically think being alone is bad , it’s not ! being alone and happy is far better than worrying about some man who sounds like he’s just using you when he’s ready too and going when he pleases as you allow that to happen – I would take charge of your life here and this is coming from someone who had a really shit childhood , dumped in boarding school and emotionally neglected – better face your demons sooner than later otherwise it’s just going to be years of unhappiness in trying to find it in other people , especially men – goodluck X
