<human>: Provide a brief overview of the text.

I (24f) have been seeing this guy we will call him D (31 m) for about two months now. Things started off fantastic, tons of conversation every day and we consistently see each other once or twice a week. He's given me no reason to doubt him or think he's up to anything suspicious. 

Some back story on me. I was in a previous relationship with a guy who I will call A (28m) for six years. This relationship was the worst thing I've ever been through. Mental abuse, being used as an object, passed over for the bars and other women...you name it I've been there with A. When I finally grew a spine and moved on he didn't and still isn't handling it well. 

Back to D. I feel incredibly happy anytime I'm around him. I feel like he actually listens when I speak and makes me a priority. He is slower moving into serious relationships than I have been in the past and although I completely understand there's that part of me who has been used and abused who is afraid it will happen again..and anyone who has been through something like I went through with A will understand how hard it is NOT to put off past hurt on new relationships. 

I don't know how to slow down my feelings or contain all my old worries so they won't ruin this. I've always been a jealous person and with D I don't feel like I have to worry about it. In my gut I know he is a good person and I don't want to sabotage or be too overwhelming with all my worries and past hurt and end up screwing this up. I have a history of pushing away the good guys because of past trauma.
<bot>: I am afraid I'm going to ruin something life changing because I can't get over the past hurt I've endured.
