My bf (22) and I (21) have been together on and off for three years. I struggle with feelings of insecurity. I have been told that I tend to self sabotage. I love him and respect him so much and wish he would show me more affection. I don’t know how do ask for this without nagging or seeming like I’m ungrateful for the life he has given me. How do I get him to see me in a more positive light without nagging? I’m tired of being so emotional as I know it drives him away.
