Am i being used?

Hi

I am in a relationship if thats wot it called, I have been with my girlfriend for 7 and half years a cpuple of years ago i lost my mum so i moved back in with my dad to help him get through it. Since then our relationship has been slowly crumbling away. She has started going on the internet alot and chatting to other people sending them pictures of her which are quite xxx rated. She has also became very secretive she closes any messages and deletes her txt messages when ever im around. But recently she went to meet one of the guys of the net she has been talking to. She was ment to be going up for the day but guess wot she missed the last train home. about a week after she got back she told me she was moving to manchester and unless i came with her it was over. I told her i cudn't just pack up and leave my family. So she split up with me, then she decided she wanted to give it another go but she was distance with me, then she went to stay at this guys house for 3 days again, in which she was very distant with me and hardly spoke. When she got back things neva changed she was still very distance. So i decided we needed a weekend away just the 2 of us. It was great it was like old times, until we got back, about 2 hours after we got home she told me she was going up to see this guy again and she was going to be staying there for a week. I expressed my feelings about how it was making me feel but she just didnt care and told me it was over. Anyway then the next day she tells me she wants to just see me, which is very hard for me because i love her. I met her after work and we went for a drink, she was just like the person i feel in love she was all over me telling me she loved me, we even fooled around abit when we got home. We made plans to meet again yesturday after work, then yesturday during work she sends me a txt saying that i shudn't tell her that i love her because we are only seeing each other and its not a propa relationship, Then i got a txt saying that she wanted to cancel the plans we had for last nite but it was too late by the time i got it i was standing outside her front door. She lets me in but i can tell she doesnt want me there by the way she was acting, so i had a coffee and left. I feel so unloved and unwanted, WHAT DO I DO, i love her so much but cant carry on in this 1 sided relationship

you are totally beinbg used man there is no doubt about this .....she has cheated on you and you cant even see this if my bf said i am away to see a girl for the day i would tell him not to come back....am sorry to say this but why didnt you just say that i mean are you some kind of push over and then missed the train what a LIE i would have travelled right down there and broke up with her ass....i know you love her but if you dont do it now then you will get hurt even more in the future and it will be your own fault .....she is going from one guy back to you again.....you see i met my bf on the internet and me and him ave small little rules like dont send pics to ppl and no web cam it keeps things easy......one timne he wasx talking to a girl he used to flirt with before i cme along and she was bit of a slut....i found out he was talking to her more and things they said to each other upset me cuz he was talking to her behind my back i was going mad in my head it out blow out and for a week we were touch and go i said if he continued i would break up with him......he stoped it he broke dwn saying he loved me so much and couldnt lose me....anyways from your story your gf is so selfish and playing you there is only 1 thing you can do is leave er because this isnt love....dont blame yourself about your family is she loved you she would have stuck by you not go behind your back.
