I take things the wrong way & stay angry all day. How can I stop this?

I'm very sensitive. More sensitive than my boyfriend. I don't know why, but I take a lot of what he says the wrong way. I totally read into everything & think he was being rude or implying something that would hurt my feelings. I then immediately become standoffish & try to think things through before I confront him to make sure that I'm not over reacting. But still, it makes him feel as if I think he'd be so mean to imply the things I think he's implying. The thing is....is that he's the best thing that has happened to me & the nicest guy in the world. There's a kicker, which we both think could be contributing to this.... My last boyfriend was very abusive both physically & verbally. Since him, I think I've become extremely sensitive & vulnerable & wear show my emotions in the open frequently. I don't think he's like my ex-boyfriend, but he feels that I look at him as if he's just as bad. I also deal with things differently than he does. He can let things go easily. I'm just the opposite. I stay angry all day. I wonder if this has to do with the ex-boyfriend too. I don't think boyfriend is mean at all! I just don't know how to relax, take things with a grain of salt & let things go. Please give me adivce. I'm currently unemployed & am waiting to see how much low-cost therapy would be, but haven't gotten a response. I also ordered a book online, but it hasn't arrived. This is my only shot at some instant advice. I'd be grateful! Thank you!

dnt take thngs in a -ve way,forget abt past cmpletly
do not thnk much of being relax,instead enjoy the present momements
life bcomes the way you look at it,so spread love on ur partner nd stop looking ur present wth past's events
if ur partener does nt bother abt small thngs ,u shud also nt be bothered,

No you dont take things the wrong way, your partner should be respectful to your sensitivities as im sure you are sensitive to his, any relationship is a bout communication, there is a reason he and you picked each other so focus on the communication and i would suggest you be like me and read self help books at the library and most definately put a job as a high priority, you stress more when you are not working, get a job and things will fall into place if you read books and spend time on yourself and explain to your boyfriend that
you are trying to become the old you before the previous relationship. If he dosnt support you, plenty of fish in the sea after you sort out your psychological issues. brilliant book that can change your life "Are you the one for me? Barbara De Angelis......
