This guy I used to work with over 3 years ago invited me to visit him in his new state. I paid for my flights and some meals. He paid for hotel, some meals and activities. He lives in the same city we stayed in but decided to stay in hotel instead of his apartment because 1) he didn’t have time to clean the apt and 2) he wants to stay in a hotel to feel like he was on vacation too. He got promoted and is now a general manager of a branch of the company I used to work for. I did not know whether he reserved one room or two. If there were two rooms then I was gonna ask to pay for mine. Anyway, he picked me up from the airport and drove to the hotel to change so we can go back out for the night. We ended up in the same room. Nothing happened the first night. The next day after we came back from outside, showered, and were laying down.. we got into it 🥹 he seemed shy at first and was trying to find a way to get closer. Honestly, I was waiting for him to make the first move. I always thought he was handsome and sweet. We both expressed to each other that we had a great time together and that we should travel together often. We haven’t talked since two days ago when I got back to town. I was the last one to say something and he didn’t reply. He’s been the fist one to see my stories on social media these past days. He is aware that I am a single mom of two. He asked if my kids live with me in which I answered yes. I really miss him and can’t get him off my mind. I also don’t want to show that I’m obsessed.. what should I do?
