If you want to call, or text, or whatever, then do it. Ultimately, it won't make a difference to the outcome - if he's a prick now, he'll still be a prick when you contact him. If he's a nice, but lacking in confidence or slightly shy bloke, then contacting him won't do any harm, and may actually do some good.
If he doesn't respond, or is terse, then you have a form of closure. Which I know is something that I need in these situations. Doesn't make you weak for wanting that, or a worse person than others. I don't like the 'I'm better than ever contacting a man' attitude. It comes across as overly smug, as though by choosing to contact you are somehow weak, or not quite as good.
There's no magic formula to relationships. I've had 2 (that I know of, might be more) where if I hadn't pursued the bloke, nothing ever would have happened. They admitted as much to me.
Conversely, I've also dated blokes who went a bit hot and cold, I thought they were messing me around, and they either admitted it - and that they weren't looking for a relationship - or disappeared into the ether. But either way I'd tried and got an answer, or at least felt satisfied that I'd tried/ done my best.
The man I am currently dating - the whole background to our first date would (if I posted it) have everyone saying 'oh you'll never see him again'. Our first few dates were spent at his house, for ex. But it works. It's not perfect, cos real life isn't, it's not all easy and plain sailing. But I don't think it has to be in order to be good!
Ateotd, you have to be true to yourself. If you want to send a text to give him a last chance, or to draw a line, or whatever, you'll know if it will help to do so (I know it would me) and if you honestly feel it would, then go ahead.
