I met a guy online on a dating site recently. Emailed, texted and chatted for a few days a bit before meeting up. First date we went for drinks, second date for dinner and third date at his for a DVD and takeaway. Didn't kiss until third date, all very well behaved. He was due to come to mine for dinner this week and called the day before to check we were still on. I bought food specially and prepared most of the meal in advance to save time that evening - I didn't prepare a lavish feast or anything, just didn't want to be stuck in the kitchen when he arrived!
Two hours before he was supposed to come round he sent me a text saying he couldn't make it, and he was "gutted but hey" and sorry. I replied saying "ok these things happen, thanks for letting me know". Tried to keep it quite casual and not clingy, even though I was quite cross and disappointed.
I suppose I was a bit suspicious about why he wasn't coming - a couple of my males friends are adamant he had another date, particularly as he messaged me later that evening just saying that he hoped I didn't think he didn't want to see me. Which to be sounded like him trying to keep his options open.
I didn't reply as I didn't know what to say. He messaged me a couple of times over the next few days asking about my silence and did that mean I didn't want to see him again, as he would leave me be if that was the case. I gave in and messaged back saying I was just a bit cross as I'd made the food already and he'd not given me a good excuse for why he was cancelling. I said it wasn't the end of the world and I hoped he'd had a good week. He has replied saying "I'm not into high maintenance. I don't mind chasing and making someone feel special (I know I was wrong). Where do we go from here?"
I've had differing opinions from people ranging from "he's obviously a player" (he did admit to me that he was in his younger days, maybe he's not changed after all) to I am being too hard on him and should give him a second chance but that's all.
What do I do?! 
I think I am being cautious as I have been badly hurt before and was in a emotionally abusive relationship for a while so am now quite wary. Need some perspective on this!
Perhaps there's nothing lost by one more date to help me decide?
