Relationships

Hello,

I've been in almost 8 year relationship with a man I love. We've been engaged for a year now. We have 2 beautiful little girls who are 7 and 2. He has issues trying to find a job so I'm the breadwinner. He saw a recruiter and plans on joining the army. We dont live together. I live my parents and so does he. he has doubts in marrying me and constantly brings up why should we get married? Or says you do know if we didnt have kids we wouldnt be togther, right? He has been saying harsh things to me lately. I believe I have depression b/c i take it to the heart or take it out on other ppl. With him saying these things its affecting my job 100% We have gotten into heated arguements more than usual. I just dont know if I can be with someone who bashes my every move. I cant spend the money i earn how i want to w/o something smart to say. I love this man to death but i dont know how much i can take anymore. Dealing with my crazy retail job and being ALWAYS with my kids doesnt help me relax. He keeps telling me to relax but how can i. I have a ton of responsibilities. I brought up moving in together and getting a place and idk if hes scared but makes excuses like why get an apartment and spend alot of $$ when we can get a house? But nothing. Im 27 years old and hes 25. I dont want to be living in my parents house for the rest of my life.

All i need is some advice on what i should do. I just dont know anymore.
