Hi all,
(de-lurking for a minute)
Spone re that text message. Weirdly I had been thinking earlier today that maybe LC had had a family crisis or that he suffered some mental health condition which was causing him to pull back (perhaps not feeling ready for a relationship?).
I think this is the explanation that makes most sense of his behaviour. From your description of the dates he seemed genuine and into you, so it sounded like some outside issue was the factor in causing him not to respond.
I have known people (and know of people) with depression and it can cause the person to withdraw from social contact, and also even very small things can seem too much or overwhelming.
To me that text message rings true, and I don't think he was being intentionally mean or disrespectful by not texting you earlier. Of course he could be an arse, but in the context of the information you have given us I am thinking he is genuine. He possibly felt too embarrased to bring it up earlier (considering he had only met you twice it would be difficult to bring up such a personal thing, so I suppose he took the "easier" option of avoiding).
The "a bit-low" thing, I don't read it as him minimising depression. He might have a habit of wanting not to burden people with how bad he feels, or worried that he will freak them out or something. He might also have a different measure than what a healthy person would use (i.e. he means a bit low by his standard, so not his worst, but bad by an average person's standard.)
I have a long-term (physical) health condition and you could say I do this a bit. I tend to give people information on a need to know basis, rather than giving them a more detailed account of how sick I really feel. I don't want to be complaining, or for others to feel like I am going on about it all the time, and I do worry about freaking peple out, especially new people who are not used to me.
Anyway if you do get into something with this guy I would tread carefully and protect yourself as well (I thought Wolfs post was very insightful). He may not be able to be there for you in the way that you would need, and the relationship should not be all about him and his needs. He might be lovely but not in a good place for a relationship.
I am a bit inclined to be co-dependent myself (e.g. the rescuer thing, and putting my own needs last). I'm working on this and am a lot better than I was, but no where near where I need to be. I think I would not be able to be in a healthy relationship with someone with a serious mental health condition as I think I would be constantly worried about them, and putting myself last.
Things like the erratic texting could also be unnerving as it could be hard to know how to interpret his behaviour. And some feed-back loops people normally use in relationships, might be sort of broken or absent.
Anyway didn't mean to write an essay 
Watch great to hear about the new job!
