Apparently a lot of guys are just way too busy being manly men doing big important things in the world to engage in real intimacy.  The truth is, many of you don’t actually want to be in relationships with women. And eventually she realises this, even if you haven’t.   You see her as a means to get your own needs fulfilled without wanting to reciprocate in a way that matters to her and allows her to feel like her emotional cup has been filled.   If you don’t genuinely WANT to give her the things that make her feel loved and secure, if it doesn’t bring you joy to bring her joy, then you don’t want to be in a heterosexual relationship because that is a fundamental part of being in a relationship with a woman.  You can sit there all day and tell yourselves it’s silly or that you show you care in other ways (that she hasn’t asked for) or women don’t know what they want or whatever other cope you have, but it’s still not going to stop her from leaving you when she realises you are totally incapable of meeting her emotional needs.
