<human>: I've known this guy for a long time(i'm f/25 and he's m/26), but it wasn't until recently we started talking more frequently. He recently got a girlfriend (long distance), and that's great because i like seeing him happy.

But is there some set of rules for being friends with a guy while he has a girlfriend as far as conversations go? I don't want to mess anything up by texting or calling too often, is once or twice a week plenty? 

Last time i had a guyfriend get a gf he upped and just threw me and our 5 year friendship away and i'm really hoping it won't happen with him. Plus, he just mentioned how annoying it was that one of his friends just did that so hopefully he won't contradict himself here.

Can you give me a shortened version of the text?
<bot>: Guy friend got a girlfriend pretty recently. What's a good amount to talk/text him so not to mess up his relationship but keep up with each other?
