Been speaking to a guy who I met years ago and we recently started texting. We've been texting quite a lot for 2 weeks now. Things have been going really well - it's been quite flirty, he'd always make conversation, ask me about my life, tell me funny stories in detail, send long texts, ask about my day, flirt with me, send me pictures of what he was up to - he seemed really interested and an absolute angel. Dropped hints about meeting up, making flirty jokes etc. He's absolutely lovely and he has pointed out that we are very similar and have the same interests.
But the last few days I've noticed he's suddenly a bit colder? Like, he's still texting back and starting conversation but it's less often and some quite generic like "hey hope you're alright", much less flirting and like detailed texts about his day. I don't really know how to deal with it because I really felt it was going really well? I don't want to come across needy but I was really enjoying it and it just seems he's not that bothered anymore. What do I do?
