I recently been in a 2 year relationship with my boyfriend i gave my virginity to him and put in 100% of the effort all the time he always argued about dumb things we fought alot i just dont know if its worth it anymore because im just not as happy as i used to be 2 years of arguing i broke up with him but we always break up but this time when i did my friend started to tlk to me i met him in church over a year ago and hes everything i like in a guy but not wanting to be in a relationship With him right now . And he feels the same way also.  Should i stay with my two year boyfirnd or be friends with my church friend
