What is your opinion on a guy who starts ignoring his girlfriend?

I was seeing this guy for a bout 3 weeks everything was going great! It seemed like he really really liked me than out of nowhere he started saying that he was really busy at work and he wouldn't be able to talk to me then the same thing the next night. To where it got to the was only sending me a message through facebook once a day and when I said hey what's up with you he totally cut off all communication with me. I honestly don't know what happened and would like someone else's opinion on the situation. Thanks!

red flag. he is probably seeing someone else unless he has very serious problems with health or about work (i.e. he is in prison or he is at hospital, etc). cal him and send a text "why don't you talk to me all of a sudden ? what is wrong ? " kinda text. depending on his answer, you will see what you can do. if he does not reply to it, then simply move on.

I think he is either cheating, or something in your personality is pushing him away. I would guess, the "honeymoon" stage or newness of the relationship has worn off, and he is no longer in the excitement phase.
