So, I 21F have some insecurity problems in relationships. I don't really want to go into my past too much. But I've never had anyone truly love me like my boyfriend does. I've been through a lot of different types of abuse in other relationships all my life, including relationships with my parents. My boyfriend and I have had problems that lead me to feel insecure about our relationship. He worked on what he did, and now I just know that he truly loves me and is sincere about not doing anything with anyone else or to mess up our relationship. I don't want my insecurities to ruin this relationship. I struggle with anxiety as well. I should add we also just lost two different children in two miscarriages back to back. And I've been really emotional on top of everything. What I want to know is what are some ways others have dealt with insecurity and overcoming that. && trust. I want to work on those aspects as he has worked on the things that caused them within our relationship. I love him so please no one saying end this.
