I'm a 33-year-old woman working in the same office as a 47-year-old colleague who has been displaying intriguing behavior. He is quite chatty, outgoing, and carries himself with a sophisticated posh accent. Despite the significant age gap, he's earned a reputation for acting younger than his age, being vocal, and direct, yet generally likable and friendly. Our interactions began with subtle glances last year, but we never went beyond that. Upon joining the office in January, I discovered we worked together, and although he continued to look at me, we rarely spoke. Recently, I sought his advice, initiating more conversations, and he became increasingly chatty. There was a moment when, wearing a knee-length red dress, I caught him staring, and he seemed hesitant to make eye contact afterward. About a month ago, he became more open, frequently coming to my desk to chat. One day, when we were alone in the office, he shared pictures of his dog, home-grown flowers, and vegetables. Playfully, he even hit my feet. We exchanged numbers, and he sent me pictures on WhatsApp, proving he downloaded the app, and then encouraged me to use Telegram. Since then, he's been finding excuses to talk to me at the office, often using playful terms like 'good girl good girl.' Recently, he started sending pictures of himself in suits from his mid to late thirties. While I complimented him, he also sent a more intimate picture of his thighs and legs sunbathing, which he later deleted, assuring me not to worry. Additionally, he's been inquiring about my evening plans, a departure from his usual questioning about weekend plans, though he never explicitly suggests meeting up. In the office, he playfully tries to hit or touch my feet and even waves whenever I'm near the printer, quickly glancing around. I'm unsure if these signals point towards a potential romantic interest or if it's a hook up situation??
