It sucks bro i've been there before and got burned really bad. I was with this girl for 6 years and we were planning on getting married, starting a family, and all that good stuff. One day for no reason at all she said she needed a change in her life and left me. I never cheated on her or so much as yelled at her in all the time we were together and she just up and left me so quickly with no warning or reason.
The part that sucks the most was everything I gave up to be with her. Coming out of high school I had a 92 mph fastball and had many D-1 scholarships on the table, not to mention a few looks from pro scouts. I essentially made the decision to give up baseball in order to be with her more because I thought I had something special and didn't want to lose it. I thought it was the right decision at the time and tried to be mature about things. I wanted to take the road less traveled even if it meant being scruntinized for it (which I was an incredible amount), but ironically me doing the "right" thing came back to burn me.
I have literally spent the past 4 months looking back on my life and all the decisions I have made. There were times that I contemplated ending it all because I thought the pain was just too much and I realized how badly I ****ed up my life, but came to the conclusion that it would just be ridiculously selfish and would show that others have defeated you. After all the thought I put into the matter, I have decided that good or bad, everything happens for a reason and it is these times that make us stronger. I know how bad it stings as everywhere you look you see the person you love(d). Just remember that it will make you a better, stronger person in the end. I don't have anything specific I could say to make the pain go away, its just something that goes away with time, but it does get better. The only piece of advice I can give you is to hang in there because things will get better and also remember to always try to smile no matter how bad it hurts because you never know who is falling in love with your smile. I know it sounds gay, but I hoped something in the response helped you out. Keep your head up.
