Am i the bad and how should i continue

Well, six months ago I met a woman, we talked on the phone for a month and then I went to see her at work on Friday, we talked and it was great, so I went again day later and we ended up in the car and we had sex together (i had her agreement), but I recently found out from her that I was too quick, but she didn't want anything to do with it and couldn't say no to me. She has bad memories of that and we haven't really talked for six months and she doesn't want to see me (at least now) and she says that she's fine if we just text each other, but I want to have a normal conversation with her in person but I don't want to be a burden again, what should I do?
