i have an amazing day with my boyfriend we spent all day together i would do anything for him its my first actual boyfriend and i couldnt do anything to ever hurt him. He also would do anything for me, we love eachother and havent been together for long at all. The same night i had gone out with my girlfriends and drank more than intended there was this guy i had just met and he was all over me i was regretting him like no tomorrow he was fully aware that i had a boyfriend because i had told him severe times, my boyfriend was also coming to pick me up from this "party" later on, my friends had left 15 minutes before my boyfriend came to pick me up and this guy kept insisting we hook up he was begging and begging and by this point in the night i had had one too many drinks and was stupid enough to eventually caving in. So he quickly pulled me away we had sex and split seconds as we finished my boyfriend was in the parking lot ready for me. I was to drunk to say anything in the first place i had ended up waking up at my boyfriends house in the morning with a bucket beside me.. that says something. So we carried on i did not tell him he is so against cheating its ridiculous his best friends girlfriend of 4 years just cheated on him and hes always had the worst luck himself with girls cheating on him. Hes also one of those guys that thinks highly of himself to leave me in the scums if i ever did something like that ( not that i dont deserve that after what i did) he told me before that if he found out i had cheated on him hed dump me so fast and go and cheat on and he would go and break the guys legs and the list goes ON. Today we got into a little pointless fight and he ended up coming over with flowers before he had to leave for out of town. While he was driving he had texted me asking if i had cheated and i said NO i pleaddeed that i would never do that and he said okay just making sure cause someone had told him that that night he picked me up i did. Later on in the day i woke up to a phone call by him saying he knows i cheated because suppoveily the guy who i had sex with called his best friend saying he didnt want to get beat up and he confessed that he did and apologized... i then message the guy (who i had only met once anyways) and he said he had done no such thing and that someone was prentending to be him. He then threatened and said well if your boyfriend does ask me im going to tell him the truth. After a long time of lying and pleading to my boyfriend that i didnt and wouldnt do such a thing ( now i would never this was probably the worst mistake of my life). My boyfriend apologized for freaking out on me and we called it a day. My bestfriends that were there with m for most the night dont even know the truth i never told them no one at all knows except for me the guy it was with and his one "buddy" who has had a thing for me before and has no intent on letting me off the hook. Im backed into a corner of lies that has seemed to work but it is killing me inside i always share things with my boyfriend and my bestfriends and i feel so alone and lost i would never ever ever do it again and as much as i want to tell him he will leave me in a blink of an eye hes just that type of guy. I need reassurance of what im doing is okay, he said if he finds out later on hell be so pissed off but its not like i can admit it now i have already created such an elaborate lie it would literally kill us both.
