I already cut myself , I just wanna.die
Not to diminish this, but you started this when you were 14 -- anyone expecting a 14 year old to remain monogamous is in for torment. It's hard enough for adults who have found their match, but at 14 you haven't met enough people to know that. Now, you did hurt your boyfriend, and yeah, it wasn't cool, you should have broken up with him as soon as you learned you weren't ready to just be with one guy. But you will move on, and so will he.
Sweetie, everyone makes mistakes. Hell, I have been married for 13 years and we both have had our share of mistakes (even a little cheating). I swore that if he ever cheated on me then it would be over. I would up and leave him without thinking twice. But the problem was that I loved him too much to let that indiscretion stand in the way. I was so miserable without him and the truth is that I can't stand the thought of someone else having my man. I started giving him a little more loving and showing him more attention and his desire to wander was nipped in the bud. If you can work through the hard times it will make your relationship stronger. It takes time to build trust back up. If it is meant to be, you will work it out but if life has other plans for you then it won't. The point is that it isn't the end of the world. You are pretty and I doubt you have to work too hard to catch the eye of a man. I hope it works out for you. Oh and I have no idea what PCOS stands for. LOL. I am new here.
