There are a few key signs to determine if your husband is still in love with his ex-wife. If he talks about her frequently and always has good things to say about her, that's a definite sign that he might still have feelings for her. Another sign is if he tries to stay in touch with her even after the divorce is finalized. If he continues to send her text messages or emails, or if he shows up at places she's known to frequent, then it's likely that he's not over her yet.
