So I've been seeing this guy for 2 months I wouldn't say we are dating it's all very casual, I always go to his house and have been about 5 times always on weekend due to different work schedules. A couple of weeks ago he fell out with me because he thought I'd stayed out all night when I didn't reply which we sorted out, then he fell asleep when I was due to go to his place resulting in me not going obviously I wasn't happy and told him this and everything was fine after until the Monday after he didn't text me in the morning as he usually did and hasn't been texting me as often as he used to, should I be worried or am I overreacting?
I've never spoken to anyone for as long as this before as I've never been in a relationship so this is all really confusing, any help will be much appreciated.
