To help, we’ve put together a list of signs your girlfriend might be sleeping with someone else. Read what to look out for and what to do if he cheats.
Is your girlfriend overly angry or hostile? Unusual behavior is a direct sign that something is wrong. If your girlfriend meets someone else, she starts randomly fighting with you or turns her head in an unusual way. These may be signs that he has broken off the relationship or is exaggerating his guilt.[1]
Think back to how he acted. The best way to tell if someone is lying is to look for differences in their behavior.[2]
Acting differently doesn’t mean she slept with someone else. You care about her, so sit down and talk openly about her condition. Sudden mood swings can be a sign of a deeper emotional or physical problem.
