It would eb easer to break up with him then wait until he might cheat. Just tell him your miserable and work for a mutual breakup - may hurt less. It's rarely easy.
I'm with Stalk on that one...never easy, but Hell, it feels like heaven when you're finally out. Best decision I ever made was to leave my ex of 8 years. Now, I've been with my soul mate for 6 years (and counting) and I've never been happier. good luck whatever you decide to do.
if you're miserable and it is within your power to remove the source of your misery, not doing so is madness.
god this is ridiculous! we're fighting every day over nonsense. he treats me like shit, and i treat him like shit. occasionally we can put on the happy face and get through another day... but here are the reasons why i feel like i can't leave: 1. we live together in an apt, with both our names on the lease. i have to live in madison because i go to school here. because it's a collage town, mostly all leases start on aug. 15th - so neither of us would be able to find another apt any time soon. 2. we don't have very many friends, and the friends we do have don't give a shit about either of us. i don't have anyone i could move in with, and nor does he. (i have a self diagnosed social anxiety - so it's hard for me to make close friendships.) 3. i can't afford an apt on my own. 4. this might sound crazy, but he has a cat that i am very attached to. 5. i love him...certain aspects of him. ugh...i just don't know what to do.
why don't you break up and live together as friends? It might take all the tension off of the relationship if you guys aren't actually in one and you can get on with your lives once the lease is up. It'd probably be a good idea to refrain from dating during this time, but really, if you don't like being with him, don't be with him.
I don't think you need a reason to break up with your boyfriend. You just break up if you're not happy and that's it. Feelings are illogical, after all, aren't they?
