Im really struggling to bond with my partner's daughter even though I live with them for over 3 years now. I cant let her in. I cant return her hug and kisses. I only react to her when she does something and thats upset me. I only react for the negatives. This puts lots of pressure on my relationship with my partner. I used to work with kids and I never had an issue with bonding or giving hugs and kisses. I cant have children and I felt so lucky when I met my partner who was a single dad. I was over excited to meet her, and become a mum. Now I have it and I cant appreciate it. I do take care of her making sure she eats, drinks, sleeps enough. She has nice things to wear and making sure she does well in school etc. but Im not capable of love. Im upset with myself and I dont understand why it is happening to me. I want to let her in, I want to love her but something is blocking me to do that. Im worried if I dont change I might lose my partner and her. I dont know what to do
