I think my GF is cheating on me?

[Natalie]

As hard as this is going to sound I think she either is talk of or meeting someone else or maybe she is just not feeling the same way about you anymore, when I was with my ex we used to see each other all the time he was in the army so only saw him at weekends but every weekend without fail he would come see me, after he came back from his afghan tour for 6 weeks we went away over Xmas and she. We came back he changed, he never text me all the time anymore like we would only speak at night even though he would be on his phone during the day, when it was weekends he stopped coming to see me and then one night he told me I was boring that I don't go out anymore so I went out one night and he accused me of cheating then I went on his Facebook for the first time ever and he was chatting to a girl I kicked off and he split up with me, not heard from him since, now he still says to people now that he judt wasn't happy in the relationship anymore, split up! It won't get any better! Only worse
