i'm 31 and i've been dating my guy (36) for 3 months. i consider us very close - talk/text every day, say "i love you", he treats me great. he went away for the the weekend with a few guys. we texted a bit on friday night, then during the day on saturday. i texted him last last night to say hi, but never heard back, so i texted him again this evening. he said he was home and just waking up from a nap and would call me "in a bit". that was 4 hours ago. i'm getting worried that something bad might have happened while he was away, or he had a change of heart. am i overreacting?
