My girlfriend just dumped me! I thought we were in love but I guess not. She basically took my heart out and stomped all over it.:( While I waz being loyal to her she turns around and cheats. We have been dating for 8 months and it feelz like I just wasted 8 months I could never get back. I'm going around all depressed now and she is all happy. She has no clue how much it hurts:( What should I do? How do I handle this heartbreak?

Speaking from a mother of a teenage boy and having raised two girls. I understand that you are hurt deeply. Sometimes when we think we are "in love" esp. when young and inexperienced this kind of hurt happens constantly to someone or another. I Am assuming you are a teen?
In life we go through a lot of "things' that hurt and disappoint us... in my opinion give yourself some time to heal and try to go on with your life taking along with you more wisdom and experience and use it when you find another girlfriend or if by some means you and she get back together and keep your eyes and ears open .
Hope this helps you :)
Good luck and God Bless you
