Basically, I found out off one of my my boyfriend’s ex-mates that my boyf had kissed another girl when ‘spiked’ with drugs such as ket, pills etc. on a night out in town. Me and all my friends, including parents were very shocked as this was very surprising to hear, considering how caring and loving he is to me. My boyfriend didn’t tell me this himself as he ‘didn’t want to hurt me and didn’t think it was true’, so some of his mates told me what happened. I found out it happened about 6 months in to our relationship, and this was around the time of his 18th birthday, so he was new to going out in clubs. I spoke to my boyfriend and he told me he had blacked out completely that night and didn’t remember anything from the night... I also questioned the girl nicely, and she told me a complete different story to what his friends had told me, telling me he was following her around and trying to dance with her, so she told me that she thought if she gave him a kiss that he’d leave her alone... but who would kiss someone if they’re bothering you???? Anyway, she also said to me that he looked out of it and to forgive him because it was a little peck on the lips and nothing more. I decided to give him another chance on the basis that this was a one off, and that there was nothing else he was hiding from me. He told me at this time that he had been told there ‘might’ have been another girl who he had kissed, but wasn’t sure. I decided to leave it and have a fresh start with him... only to be told a year and a half later the full story, in which his mates told me that he had been dancing with his friends in a club, and a group of girls came near them and started dancing, one thing escalated to another and one of the girls apparently lent in for a kiss with my boyfriend, and then his mate supposedly pulled him away and they left. My boyfriend told me that he didn’t even remember if he had kissed her or whether it was a dream (obviously we confirmed it was true by asking his friend), however he told me he had been egged on to do certain drugs that night too. My boyfriend is quite a ‘lightweight’ when it comes to drink and drugs, so I do believe that he didn’t remember/intend for these 2 occasions to happen, however I can’t stop thinking to myself that if he loved me he wouldn’t have put himself in the same situation after the first time?? I just don’t know what to do because I don’t know whether I should let it go or whether I should split up with him as I will never know if they’re the only 2 occasions, as I originally only found out due to his friends telling me ( a year later ). Can I also note that some of his ‘mates’ are quite sly and snakey, so I don’t know whether I believe what they told me or whether they were trying to cover up for my boyfriend, however thankfully he’s not friends with these people anymore. Also note: my boyf has stopped going to clubs without me now so I believe he is as sorry as he tells me he is?! Advice pls??
