4. He’s Not as Affectionate
Affection is important in any relation. Any changes in the affection he gives you can point to signs he’s losing interest. If he’s never been super affectionate or hands on, you likely don’t have to worry. If, on the other hand, you’re used to him holding hands with you, giving you hugs, and kissing you and he suddenly stops or really lags, then there could be a problem.
