hi guys, im new here, i found this site by typing in "how to find out if your girlfriend is cheating on you" in google, anyway, i have a little problem, im going out with a girl, kirsty, who is my age, we have been together for 3 and a half years now, when we first got together, for the first year she cheated on me a few times, she even lost her virginity to some boy younger than me, she used to have barbeques every few weeks, and invite every boy at my school apart from me, her parents hated me, i wasent even allowed to be with her at one point, she had this group of friends and they used to go to a local club called thursdays, these friends disliked me aswell and used to encourage her to cheat on me and kiss other boys at the club, anyway, after many many arguments and discussions, kirsty promised to never cheat again, and as time went by she got hooked on me and fell in love with me in quite a big way, i could tell she loved me and could tell she really did regret cheating on me the many times that she did. anyway this was long ago now, and deep into our relationship kirsty mostly stays at home doing coursework for school, she stopped hanging around with the mates who hated me and was more interested in learning how to drive and getting a levels at school. she only goes down town and to supermarkets etc. now every woman is entitled to a night out, and im not a jealous guy, but she went to a party last friday evening, and this was the first time in years shes spent time with the group of friends who dislike me (the ones who used to encourage her to cheat) anyway she said to me after the party finishes, she is getting a lift home at half past ten that night from her sister, while the friends go to an over 18's club called shieks down town, now when i have kirsty at my house on a usual friday evening, she is gagging to get home and moans that she has work early next morning. i txted her night at 12 o clock that night and went to bed. in the morning i had a txt and i didnt get the txt till 4 am in the morning, now my girl kirsty always is in bed real early, and it was so odd she hadent gone to bed till 4am, the txt said her battery went in her phone and she was sorry she didnt txt me goodnight. i then thought it was obvious she went to the club with the group of girls, after several strange txts she admitted to going to the club shieks, telling several different stories about her phone battery, one txt saying i turned my phone off coz it was about to go dead coz the battery was low, then one saying the battery went dead, then saying the phone wasent off at all, since that friday evening when she went to that club with the same group of friends that back in the day hated me and encouraged her to cheat on me, she has acted very strangely, short blunt txt messages, a different approach of how she usually would act round me. because she has cheated so many times in the past, i dont know whether im being paranoid or did something happen that friday night at the club?? i need to guys advise, has kirsty changed or is it just words, did she cheat and how can i find out?????????
