I’m sorry for what you’ve been through. I also struggled bc when I was younger my parents were only affectionate with my younger sister. I struggled in relationships bc although I’d tell my past partners that I liked them they didn’t see it bc I was very cold and was not affectionate. The important thing was that I noticed my pattern and I tried to hard to change it. However, I did have a daughter at the age of 18 and I made sure to give her all the love I never got. Till this day my kids do get many hugs and kisses, bc I feel like they’re mine so it’s different and they deserve to get the love I never did. On the other hand with partners it took some time I had to tell myself “hug them”. It was weird. When I married my husband I became more affectionate but he came from an affectionate family so it bothered him. I explained my past (I was never abused). In the process it did hurt my husband but we worked on it and now I’m more affectionate. I hope this helps.
I feel the same about giving affection to my kids. God bless your family, I think being conscious of an issue means you can work on changing the behavior that isn’t working for you! No body is perfect! As long as you’re doing the best you can that’s all you can do.
