ethical

i know thats the reason she left for that weekend was to see if she could have something better or someone more compatibe, but she didnt so she came back to me. now after three months she is breaking up with me again. I dont think(yet dont know) if there is another guy involved here. i was her first EVERYTHING she was 15 and i was 17 when we started going together she is now 20 and im 23 and things just seamed all messed up. do you think i can get her back should i try?? when i asked her to tell me why she broke up with me she said she didnt feel i needed an explanation. im not going to lie i have done some wrong things through this relationship aswell but now have put all my heart into her, we both like different things about this world I like hiphop she likes rock i like blue she like red etc... can two people like this work out? can i change all of my ways to be the man she wants to be with? do i have to do this to get her back?

its imposibble to get an STD from sucking on a girls (*)(*)

I have been with the same girlfriend now for 5 years, has been some what of a rocky road, but we both have had our ups and downs . but recently is when my world came crashing down on me. Was about 4 months ago back in may me and my girl had split up, she said she needed time to herself and a break from me. she left for one of those weekends within that month to a guys house who lived far away. she went with another guy friend. she had slept with this guy before (the one she went to visit)one time when we had broken up for a day he was at some party and she ended up sleeping with him, so when i found out were she was going for the long weekend it killed me inside (it acually felt like some one had stuck a knife in my chest). so anyways she comes back from her little journey and about a week later calls me up. She says that she had to go there to see what her real feelings towards me were and that she has decided she wants to be with me and spend the rest of her life with me. we have been together ever since i forgave her for this and thought ok mabye she really does want to be with me. 2 days ago we go to a club and get in a small pethetic argument because she thought i was looking at another girl (i wasnt) she does this all the time and it gets annoying. when we get home she tells me she does not want to be with me anymore and she is not happy being with me. at the same time I love her to death and am happy to be with her 24/7 doesnt make sense she has been diagnosed with bipolar disorder and i have a.d.d cause's me to not pay as much attention to her when she talks but i do it to everyone cant help it. she is saying we are 2 totaly different people and it could never work between us, WHAT DO I DO?? do i try to get her back? can i get her back? should i just move on with my life and try to forget about her? I cant stop thinking about her since she broke off wit me i cant eat sleep drive work or anything its tearing me up, some suicidle thoughts but doubt i would go through with. i mean this was the person i wanted to spend the rest of my life with what can i do ..... PLEASE SOME ONE HELP ME
