Iv been in a relationship for 10years and iv caught him on sexsites n stuff lots off times but we have tried to get through it but we don't live together but I do love him so much but am just not happy anymore in myself iam scared to let go as I will be totally alone as iv no friends but iam scared to break my own heart as he's my best friend aswell .iv been drinking n stuff and I know that's wrong but the question is is love enough ? He does love me that I know but it's the worry off being alone as it'll be like he's dead to me n it scared me
