My cousin, who is like my best friend and a bridesmaid in my wedding(would have been moh but she couldn't with where she lives right now and school) isn't talking to me now and is upset with me because i haven't left my fiancé.. We've had a lot of problems over the past year and a half especially since having our daughter and I've been pretty unhappy. But my fiancé agreed to go to counseling with me to work on our relationship because we love each other and want this to work for our daughter.. I don't know what to do or say to get her to talk to me again...I really need her right now since my mom is moving 9 hours away this weekend...
