What is your thoughts if you saw this posted on Facebook?

Yesterday afternoon I had a missed call from my fwb. He called me but I was working.I returned the call through Facebook and he didn't answer. Later on in the day I am at my second job. It was close to 9 pm.I was on Facebook on the regular home page and I saw him come up. He posted this. Facts, fellas if her conversations is getting shorter with you it's because they are getting longer with someone else. It could be God or Bob. I don't know and it was an emoji of hands up saying I don't know.

Ok so who is Bob? Bob is my other male friend but I haven't seen him in a while.He doesn't know him but I always communicate with him on messenger.I have no clue if it's a connection or what. My co workers ask do he know Bob I said no.

Serious thoughts please that could help.
