I have been dating a guy for over a year now and I can't seem to cope with the fact that he had a life before me that involves an ex wife and two kids. I absolutely adore his little girls and we have a great relationship, as well as a great family dynamic at our home. However, I'm 23 and am new to dating someone that has been married before. In my past relationships, there was a ton of infedilty and I was taught that keeping in touch with exes is terrible and leads to infedilty, so coming into a relationship where my new guy has to keep in contact with his ex wife for co-parenting purposes causes me great anxiety. Not to mention that the ex wife is constantly making passive agressive remarks toward me to remind me (as if I need a reminder) that they are their kids and that she knows my boyfriend extremely well and basically anything else she can throw in my face to try and piss me off. I have issues with trusting people because of my past and I also have trouble with insecurity, so it's the perfect storm and causes a lot of issues between me and my boyfriend. He is the most faithful and loyal man I've ever been with and he is definitely who I want to spend my life with, but if I don't find a way to cope with the fact that he had a life before me and that now he has to communicate with his ex for the children's sake, I'm going to ruin the great thing that we have going. Anyone have any advice on how to cope and get past my insecurity in this situation?
