Context: left an abusive relationship last August. Ex was a coke addict and borrowed money off me constantly for various reasons/excuses. I was a mug and felt like one, hated myself for saying yes.
Now: made friends with a guy at work. He seems nice, bought me a cinema ticket when I was feeling down and I had a nice time. He's also complimented me a lot. Don't know if there's anything romantic there. We've probably been friends for about a month at most, before that we were colleagues.
Today he messaged me asking to borrow £50 and it's set all these alarms off in my head. He wants to borrow until Monday (payday). Affording it isn't the issue, I'm more suspicious of why he's asking me and what this means.
Am I being overly suspicious or is this weird behavior on his part?
We are both doctors but I'm part time, so he earns probably £5k a year more than me on average.
I think that's all the relevant details.
FWIW, I really don't want to lend him any money. I'm just feeling put on the spot/guilty and unsure how to say no.
