My girlfriend and I have been together for almost two years now and she lost her job and moved in with me right before Christmas. Just about every month for the past five months or so we'll get into a big argument that she starts and it's usually over something really dumb. I get enough stress at work from my employees and I don't need any more when I come home. She's threatened to leave me a few times already but then she changes her mind and starts crying and asks me to forgive her. I love her to death and I'd like for our relationship to work but I'm just so tired of all the stress she causes me. What would you do?
