Need help/advice

Ashley
Okay so me and my bf have been together for almost 9 months and we fight constantly anymore and it's not really his fault we both have really bad trust issues and he also has mental issues he's on meds for so his medications sometimes effect his moods and stuff plus we pretty much live together with his family so there isn't much privacy or anywhere for him to be alone like he wants sometimes but any advice for trying to limit our fighting and everything it's mostly over stupid stuff like the tone of his voice sounding pissy sometimes makes me feel like I am annoying or something and that starts a fight or other times it's just me asking if he loves me too much or not trusting him that starts it and he talks about our future sometimes like marriage and having our own place and kids and stuff and he has also told me if he didn't love me he wouldn't be with me and stuff and he has never done me wrong so I don't have any reasons to not trust him but yet here I am always worried about what he's doing while I'm at work or waiting until he's asleep to check his messages even thou in my head it's like if there was something on his phone he probably already deleted it before hand and stuff but like idk I just need a way to stop the fighting and all the trust issues I have :/ I wasn't like this in any other relationship...I used to be the girl that just let the bf cheat or not care what he was doing and idk if it's because my current bf is my longest relationship or what but with him I'm always afraid he will leave or cheat even when he says all the time he won't :(...
