Morning ! This is my first post. I am a bit stuck on a simple issue that I can’t figure out so would appreciate your opinions please . My male friend and I have been friends for years . He has a pgirlfriemd if a few months . He seems happy .however he has started a new habit over the last few months which I wonder is a bit strange . He obviously doesn’t contact me when he is with her but when she leaves his home , even if it is 7 o clock in the morning or 12 at night, he starts sending me the most mundane stuff eg funny’s, memes, jokes etc. We work together now and again and he will message me every single day after work . Again , nothing sinister or untoward but it will be him, probably out of habit who starts the conversations between us. I don’t initiate and I don’t always respond as I’m busy in the evenings. Aibu to think this is bizarre . Or am I overthinking this ? Thanks
