I've been dating this guy for a few months. He's really really nice. I've had a had history with relationships. Constantly have ended up with abusive men. My last "relationship" ended when I realised he had stolen over 400 pounds off me. The ex before that physically assaulted me many times. You get the picture.
The new man I am dating is totally different to what I have experienced. He's very respectful, has paid for all our dates, and calls me for conversations most days. He's introduced me to his brother and his friends. And he's planning a weekend away together. Although we've been on 4 dates these have spread out from 10 hours to 15 hours long 
I really really like him. He's said to his sister that he "doesn't want to fuck this up" and that he thinks im out of his league.
He lives about 1hour 30mins from me but travels to me at the weekend.
We haven't slept together yet (whicj I like and is out of the ordinary for me), but he tells me he isn't dating anyone else.
It's going well basically. But I have a horrible nagging feeling that he's about to finish things... Nothing has changed. He contacts the same, our intimate levels have increased and we are very touchy feely when we're together. I just can't explain why I feel so bad about it 
Im waiting for him to arrange this weekend, which he does each week. He's working at the minute and it's usual that he doesn't text me until he goes to bed. But I feel so on edge that he won't arrange it.
We kissed lots the last time we were together, and I've convinced myself he's going to pull away because I'm a bad kisser (I'm in my 30s,i know that makes me sound like a teenager!)
He text me this morning and he will text back tonight.
How do I stop the anxiety 😔 I'm going to ruin this and I don't know what to do. My mind is ruining a good thing and I feel so frustrated by myself. When I feel like someone is about to leave me I distance myself l, but I don't want to push him away.
Please help
