So my boyfriend and I have been dating for over half a year but we have decided to have a "break" from our relationship as we were arguing a lot. For example, I've just finished my university exams and he would get annoyed when I spent the whole day studying. Also, he often tried to sleep/ make out with me when we went to bed but I wasn't in the mood because I was stressed about exams and that made him really moody with me.
Anyway, we decided to go on a break as of yesterday but I'm not really sure what he means by break. I went to my best friend's house party last night and ended up having a panic attack in her bathroom. A guy (who happens to be close friends with my boyfriend) came in and he knew I was having a panic attack so he knelt down on the floor next to me and did deep breathing with me until I calmed down. He also wrapped his arm around me and I lay my head on his chest and I felt a warm fuzzy feeling in my stomach.
He asked me if there was anything he could do to make me feel better and without thinking, I said "kiss me". He looked shocked and asked about me and my boyfriend and I told him we were on a break.
Then he hesitated for a moment before saying "well as long as this will make you feel better" and he started kissing me. We lay on the bathroom floor like that for a while and honestly, it felt like he was my boyfriend in that moment. I tried to unzip his jeans (I was quite tipsy) but he said that he didn't want to take advantage of me because I was in a vulnerable position. He has always been nice to me but I've never seen him in a romantic way until now.
I already have his number and he texted me earlier to say that he didn't mean to come off as rejecting and that if I was sure that I wanted to sleep with him then he'd be happy to. I feel like I really want to but then I am worried about being disloyal to my actual boyfriend.
Would it be bad of me to do this during our 'break'?
