Feeling Guilty

I tried online dating because I had been in a no-label relationship with my friend and I just wanted to meet someone out of my group of friends. The first date and only date I picked went well-he said he was looking for a relationship and that I seemed very cool. He asked about some things that were usually deal breakers for other people he dated and asked what I was looking for in a relationship. He came by 3 days in a row and I said hey next week when you stop by we should be more physical and he agreed. So that Friday comes and right before he’s supposed to come over he says his sister just got out of surgery and he needs to take care of her and then he says he can stop by after she goes bed, then he says he has a headache and then he randomly showed up at 11 pm and things got physical. Later in the weekend he says I had to take my sister to the ER all night -she gets anaphylactic shock 3 times a month and has to go to the ER and on Sunday he said I’m going to stop by after I take a nap and come after-so I cancelled an Oscar’s Get together, and told 3 people not to stop by my house-4 hours later I sent a text saying my door is open if you’re stopping by he never shows up. 17 hours later Monday morning-he sends a sorry I overslept yesterday-how did you sleep text? I’m like terrible-but I’m trying not to overreact. He offers to come that night, but when I mention I have my kids I don’t hear from him and I get a few texts through out the week. I’m blocked from his facebook, have never been to his house and he says he has family responsibilities and can’t call and text. We mildly knew each other in high school. So Friday at work I get a text that says-I’m sorry my baby nephew just died, but I’d like to see you on Saturday. Something bothered me, so I told him later that night I don’t want to date you any more-something seems off-he got extremely angry and said that I was a horrible person who didn’t support his family responsibilities and he wouldn’t want to date me again even if I changed my mind. Part of me feels guilty, but everybody says I dodged a bullet.
