<human>: So here's the deal. I went to school with a guy who in the back of my mind, I thought was cute. Nothing ever happened between us. Fast-forward about 10 years and we run into each other on an online dating site in December. We get on well, have a bunch of mutual friends and have been getting on well ever since. 

Anyway, this weekend we were flirting and he was hinting at sex and because I don't have sex outside of a committed relationship (personal choice as have been burned before) I decided to ask him why he was online in the first place, what was he looking for etc? He said he was looking to meet people and see what happens, for something that is easy and that he doesn't have to work hard to make happen. He also said he's never been in love before. We then talked a little bit more and he said the following:

"Okay, Hannah, I think I should be entirely honest with you because you seem like an amazing girl and I really don't want to hurt you. Last year was utterly horrible for me. I lost my mum and last grandparent. My head is a bit messed up if I'm totally honest. Can't picture falling in love/being in a relationship. Reasons why I don't want a relationship where I have to work at it as my patience is not where it once was. Just want something chilled where I can grow into it. I just want to be honest with you and apologies for not being so before. Just a hard thing to tell anyone as it changes everything."

Just as context, he is a great guy and he's everything I'm looking for at the moment. I'm just really concerned that he's emotionally unavailable, just wants something casual etc. I'm happy to be there for him as a shoulder to cry on etc but I don't want to put myself into a position where I'm going to get hurt myself. I have been burned extremely badly before by unavailable men (commitment problems, addiction etc) and hope I'm not repeating my pattern by attempting this. Basically my question is, should we EVER try to date someone who's just lost their mother?

Can you give me a shortened version of the text?
<bot>: I like a guy whose mother died recently (2015). Should I even try to date him or is it totally the wrong time?
