"I think he lost interest in me," said the woman confused with her relationship. No one wants to believe that the man that they love is drifting away. You keep coming up with excuses for why he seems distant and preoccupied. You've probably asked him what's bothering him but all you get in response is that everything is fine and you have no reason to worry. You are worried though because you don't want to even imagine for a second what your life would be like without him. If you do have nagging doubt in the back of your head about how invested he is in the relationship, there are some signs that will help you clarify things. If you notice him acting in specific ways, you'll know for certain that he's contemplating breaking up with you.
You can typically tell when a man is losing interest based on his desire to be around you. We all remember what it was like in the early days of our relationship when our guy would do anything in his power to spend just a few minutes with us. Obviously that does change as a relationship falls into a routine. However, if your boyfriend suddenly is busier than he's ever been or the demand on his time at work has doubled or tripled, don't overlook that. A man who is deeply in love with his woman won't let life get in the way of seeing her. He'll do what he can to spend as much time as he can with her, even if it means rearranging his entire schedule. If your guy doesn't plan on seeing you for days at a time don't fool yourself into believing his life is just too full. It's not. He's likely avoiding you.
Starting right now stop telling him how much he means to you. This isn't part of a ploy but it's more of a test. We just don't take the time to notice who expresses what they feel first. If you're the one telling your guy that you love him and then he responds that he does too, that's actually very revealing. If you stop saying anything about your feelings, you'll get a good sense of whether or not he's feeling anything significant for you still. If he doesn't ever tell you that he adores you or he never says how lucky he feels to be with you, that suggests that he's not feeling close to you. You shouldn't have to be the one to always say you love him first. If you are, chances are that you love him a lot more than he loves you.
It's also important to pay attention to your guy's body language if you suspect that he's pulling away. If he's feeling emotionally disconnected from you he'll be much less inclined to reach for your hand to hold it or to put his arm around you. The frequency of your intimacy is also a great barometer for where his heart and head are. If he's not desirous of being close to you physically, that's a reflection of what he's feeling emotionally.
