UPDATE:
He ended up answering me and he was really nice about it all but he said that “things have changed for him” so that the doenst think it would work out. He wants to explain to me in person what has changed for him so I’m assuming he’s going to tell me when I see him next at work. I’m sorta nervous; Idk why he couldnt just tell me whatever he’s gonna say over text message you know? It just seems dramatic to make me wait until I see him next for him to just let me know why he’s changed his mind. I honestly don’t think the situation is that big of a deal. Yeah I’m a little disappointed and my pride is a little hurt because I put myself out there, but at the same time I was only suggesting a fwb, not like proclaiming my love for him anything crazy. So I really don’t think its that big of a deal. However, I am curious what he is going to say. I feel like he’s gonna tell me that he’s dating another girl now or he’s getting back together with an ex gf or something. IDK why he couldn’t just text me that though, it will probably be more awkward for me if he says that to my face. Now I have to prepare myself to just “be cool” and nonchalant about whatever he ends up telling me. :/
