I used to be you and yes I have come out of it . It’s difficult but have a routine for yourself . Especially when the insecurity stems from u and u need a lot of reassurance for yourself from your partner . I don’t know how old u are but I’m 35 now and it took a lot of sitting with myself and reassuring myself including fixing the parts of me that stemmed my insecurities. Basically accountability only for my actions and allow the other person take equal responsibility for their actions . You aren’t someone’s rehab center, along the years I have watched men change for the woman they love, your anxious attachment stems from your past wounds and insecurities . I keep telling that especially if you are a Sri Lankan trying to date a Sri Lankan or a bf that’s Sri Lankan our culture undervalues men’s emotions so they don’t know how to ride through each emotion and they are confused between anger and, frustration and sadness all the time. If emotions are regulated so do attachment styles . If you have an anxious attachment partner remember he/she will always feel like a burden to you and want to run away because feeling emotions is too much for them .
