I feel so stressed staying with my boyfriend  

Yes,what you said here was similar as what he told me last night. He asked me to give him sometimes because he needs time to adapt with the job. He was just being transferred to a new branch,the workload has increased a lot compared to the previous one. Maybe I should be more patient on this matter. I really love him very much but sometimes when I am having my mood swing,I tend to throw my temper on him. I an wondering whether I am doing the right thing or I am being so childish on this matter. I find it so hard to sort out a way for me and him.

Just be patient and give him time to adjust to his new position at work. The worst thing you can do is get mad and take it out on him, he doesn't want to come home from a stressful day at work just to hear you complain and fuss about it. The one thing I have always done for my s/o is make sure that home is his safe haven, where he can unwind, and have no drama, he gets enough of that at work. Try getting a hobby, there are so many and there is always ways to do a hobby without spending a lot of money. I do scrapbooking and love it, it's relaxing and I can do it for hours, I also have orders for a girl's softball team, individual scrapbooks for the players. So now I have that to add to my scrapbooking to keep me busy. I can't do it for as long as I would like at the moment, I injured my wrist at work, so can't work on them as long as I would like. I think if you find something to occupy your time when he needs some down time to himself, you will both benefit from it.
