1st bf i broke up after 10 months and 3 weeks. at first i thought i didnt love him anymore but then later on i realised that this relationship wasnt bringing anything new to me. there was no sex, no intimacy, nothing. we were arguing a lot and even tho i loved him, i had to break up. i knew things had to change around the 9th month but since then he left for one month and then i decided to give him a last try but it still didnt work so i had to end it. also i felt really really bad cuz while he was gone i cheated on him once

well actually he had just came back and i was seeing him the day after.
2nd bf after 2 months. he was a former bestfriend. broke up because i never loved him and from bestfriend to lover i ended up hating him so much. he is one of the biggest mistakes i ever did in my life
i believe that if a relationship brings you more pain than happiness then its unhealthy and must be ended. also relationships make us accomplish self-achievement and if a relationship doesnt bring anything to you, well at some point it should be ended.
i still at this day ccant understand people who dont want stable relationships. like one of my friends told me i was wasting my young years with a serious bf. she thought i should be fooling around instead of always being loyal to the same man. but i aint like that. i need stability in my life. i cant go fuck around like my friend does. maybe that why i see them less cuz my friends are more or less all like that. they go clubbing to make out, i go clubbing to have fun and good laughes. okay now that i typed all this i realise its off-topic but whatever.
oh and i think people break up either after 2 months (like my friends just did last saturday), or after around a year or after 2 years. thats what appears to me to be the most common.
