Hi Carly, just come by for a catch up. I've known blokes like him,think they can ring up anytime of day or night and be available, like they are doing you some great favour. he's a twunt !! Dont feel rubbish, the only time you are entitled to feel rubbish is if you say yes !!
look at it this way -there's a reason he's seen as desperate and there's a reason he's alone at 4.30 in the morning !! You are worth so much better.
Now forget about him and enjoy the rest of the weekend !!
