no, may be very into you but can't express it due to their own insecurities. It could be they are shut down due to the painful emotional experience with you. Unavialable because they have childhood/life wounds and cannot connect. unavailable because still hurting or connected to last relationship.
Ultimately, you can't tell because they are in their shell
I'm emotionally unavailable and always have been, it takes a very long time before I can show a woman that I care about that I really do care about her. I have a naturally high guard and that guards will take many months to come down. I'm a product of my family life growing up and due to being hurt a few times by women in the past, I find that I get older and the more I realize that I don't need a woman the less and less I feel the need to be emotionally unavailable.
