I had just started communicating with a member, who happens to be the one I'm really interested in. My second message was long. I was texting from my phone which cuts the message at the bottom as I'm typing and can't see what it written. I tried swiping up the message to be able to see the bottom and it got sent half way.*I decided to break it up in smaller messages so I could see what I was writing. I didn't know there was a rule about too many messages to start and I got blocked until he answers. He hasn't answered and I wanted to reach out to him one more time. Could you please unblock my messages? I would appreciate it very much.*Also, I read there is a rule you cannot request phone numbers or emails. I does one begin to communicate privately then if we can't exchange that information. I'm very new to this and have no idea how it works. Please help. Thank you.
