When a woman loses interest in you, there are ways she is going to act and things she is going to do that is going to make you know that she is no longer interested in you.
LACK OF COMMUNICATION
When a woman loses interest in you, she stops talking to you the way she was talking to you before. She stops calling and texting often and also she replies your texts late. She can also go days without calling or texting you. If your woman does this then it may be that she has lost feelings for you and is no longer interested in you.
NO LONGER PUTS IN EFFORT IN THE RELATIONSHIP
When a woman is no longer interested in you, she stops putting in effort in the relationship. The relationship now becomes one sided. You may be the only one calling often, texting and also planning for dates and just doing everything to make the relationship work while she on the other end acts like she doesn’t care. If your woman starts behaving like this, she has completely lost interest in you.

LACK OF INTIMACY
Women naturally love being intimate with the person they are in love with. They love the cuddling, hugs and kisses. So if your woman is no longer interested in doing these things with you, it may mean that she has lost interest in you.
DOES NOT WANT TO SEE YOU AGAIN
If your woman barely comes around to see you or does not come around like she used to, it may be that she has lost interest. If she also gives excuses whenever you both are supposed to see and ditches dates or acts too busy at work, it may also mean that she is no longer interested in the relationship.
