Me and my fiance have been together for almost 8 years. We have 2 kids together and are currently living with her father, who literally starts shit with me because he has never agreed with mine and her relationship.

Me and my fiance have had plenty of arguments, mostly about small things like money, stress amongst a few other things. We have had big arguments too. Even when we were living in our own place we didn't argue nearly as much. Now back to us living with her father and why i don't like He invades our privacy, I've caught him several times peeking through the windows of the house one time specifically i told him not to go into the room because she had just gotten out of the shower, instead he looked through the window and waited for her to come out of the bathroom. I went and told her. Above all he causes issues and always lies legit his excuse is every time "i went in there to see if the fan and lights were turned off i heard the fan going" (we quit using the fan period 3 or 4 months ago.)

He always tries to talk to her when im not around infact when i am working he stays home later in the day just to try and talk to her then. When im off he leaves early in the am when i have to work he stays until 10 or later. He has tried several times to talk her into leaving me. He talks shit about me constantly because im a recovering addict and i did stupid shit when i was younger. He constantly lies and bitches saying we have destroyed his house. Our room is not the cleanest, it wouldn't hurt to clean it more often than once a week, but most of the time we might have a towel and a pair of pants or something on the floor, maybe a cup on our desk. when he wants to bitch he comes to me not her. Anyways he causes stress and plenty of aggravation and i personally feel like its taking a major toll on our relationship, he is a narcissist and even though he is in the wrong he says its our fault and we are wrong there is alot more than what i have described here. Since moving in our relationship has gone way downhill, our tolerance for each others bullshit has gone down. We question constantly if we should be together. We love one another a lot, we both think wed be better off in our own place. But we have doubts, i cut off most of my family for some of the same reasons. Am i right or wrong though, without so much extra unneeded and unwanted stress, is that the reason we dont get along as well. Because we are almost 100% of the time already pissed or aggravated already so when something stupid happens we just loose it?
