A guy at work was generally helpful and pleasant to everyone, often offering support. He had been especially close with a married woman he seemed to have a crush on—something that was obvious to everyone. After she left the firm, he shifted his attention to me, frequently helping me out. Once, he even asked me to buy him a £15 book in return for his help.
Recently, as I was about to leave, he asked for a company voucher, which I gave him, jokingly adding, "This will help fund your house-buying endeavors," since he’d been talking a lot about buying a house. After that comment, he suddenly stopped speaking to me, and I later found out from his friend that he’d been upset by what I said
I’d also mentioned to him that some senior colleagues didn’t like me and shared that I struggle with depression and anxiety. Knowing he wants to advance in the company, I wonder if all this together has influenced his view of me. Given how upset he seems now, I don’t understand why he won’t just address it with me directly. My mum told me that if he were a real friend, he would have talked to me about it rather than just cutting me off.
