I wanna break up with him but im not sure

how should I feel about this? like im so confused I wanna break up with him but im not sure if I should bec I love him soo much! okay the problem is this; Last sunday I had an argument with my boyfriend bec I was at his house and his neighbor came and I hate my boyfriend’s neighbor sooo much I’ll explain later why. he decided to stay at my boyfriend’s house that night I got pissed I couldnt have a good day with my boyfriend bec everytime I would talk his neighbor would interrupt and I got mad and my boyfriend yelled at me saying that I shouldnt be mad that I always have to act so stupid blah blah. we ended up fixing it my boyfriend says its his neighbor who talks to him but my boyfriend doesnt want to hangout with him bec he “hates” him too. today I didnt talk to my boyfriend for the whole day and he called and we talked for 2min bec he was going to eat he said I will call you asap bec I miss you I waited an hour he texted me saying he was at his neighbor’s playing xbox. I got mad and told him that he left me waiting anxiously for his phone call I got mad and told him that I didnt want to talk to him bec he chose his neighbor over me. now he says that I dont let him do sh*t! and thats a lie but I think its unfair that I dont do anything to piss him off or get him bothered and he can do it to me.

• why I hate his neighbor - at the beggining of my relationship he tried to take me away from my boyfriend. he also tried to tell my boyfriend to meet other girls bec I wasnt worth it. he would talk shit about me. his neighbor doesnt want us together.

btw; we are both 18 and weve been together for over a year. what should I do? pleaseee tell mee!
