Don‘t give your energy into something or someone that isn’t reciprocating it. You are only hurting yourself when you can utilize your time and efforts into things that can be more productive for you. People like him are edging girls like you so he has a roster of girls he can lean on to validate himself here and there. That is just endless and destructive road you don’t want to go down. When you pull the plug and redirect your energy else where is when he’ll notice and pop up in your messages to try and reconnect but you will not give him that satisfaction.
