I have been hanging out recently with someone I have known for a long time. We went to school together but we were both the kind of people that wouldn’t start a conversation unless someone started it with us so we never really became good friends. After school however things have changed and now we’ve started hanging out. I have strong feelings, and the outings generally go really well. But every single time it’s over and I drop her off I just get this miserable feeling on my shoulders. It’s not something I am used to with people. Is this a bad sign? What does it mean?
