Lie or genuine break up?

After a few dates, he goes away for work for five days to Monte Carlo. We've planned a date for Monday. I don't hear from him... I text. He replies saying he's had a hellish few days. Says he can't talk about it in person or on the phone. He says he will email. The email arrives finally after much anticipation:

OK, no doubt you're curious. And I do owe you an explanation. I'll apologise in advance for it being a negative one.

Right, my life before I met you. I'd basically just got out of a 3 year relationship. We were engaged to be married, only broke up a matter of weeks ago. After a bout of suicide attempts I started seeing a psychologist, and, honestly, thought I was over everything. That was, until the other night, when I woke up the next morning with the most immense feeling partly of guilt, and partly of wanting to do everything I could to get back with my ex girlfriend. I don't know what the link is, but I came back from Monaco early and went straight to her house. A guy happened to be round there, fight broke out, etc etc... but I've basically now realised I'm totally not over my ex at all, not even close to it. I can't realistically be with anyone else right now, and have also just booked myself in with Dr. Mallberg, my psychologist, for a few more sessions as I'm obviously not as mentally stable as I once was. I'll try to e-mail you again when I've got things in my head a little clearer and I can send you thoughts that I'd totally confused and muddled.

Sorry.

Worst part was I actually quite liked him.
