So I have been broken up with my ex for almost 3 years now and I have even been with my current girlfriend for around that time but I just can't seem to get my mind off my ex. I just recently found out that she is with someone and it looks like it may be for the long haul and it is really bugging me.......I keep thinking that it may just mean that my current girlfriend just doesn't do it for me but it seems to me that it always come to that point after a few years even with that ex that I am now losing sleep over........Any advice would be appreciated.......I truly am thankful for the great people on this site..........I am 27 years old and I am in school full time in a DPT(doctorate in Physical Therapy) program at NSU..........just so you understand where I am in my life.......
