1. She nags a lot
Granted women can nag and that is nothing unusual. But what you need to watch is her constant nagging. She will nag about everything from the smallest to the biggest issues. If this is happening it could indicative of trouble. She will begin to magnify her partner’s imperfections and if she is smitten by the other man she will use that as an excuse to break up.
2. The ‘We’re just friends‘ line
This is a classic explanation women used when asked about the other man. If you ask her, pay attention to how acts and answers. If she’s uneasy and refuses to give you eye contact and divulge more, chances are she is seeing him.
