<human>: I was reading the [Girls, what turns you away from guys?] askreddit post yesterday, and realized I do a few of the things people HATE, particularly the negativity and insecurity answers.

I've realized recently that I've only had two types of relationships. I've had two long-term relationships (both ~3 years) where I never felt close enough to the girl to emotionally open up to her (including my insecurities), and this inadvertently prolonged the relationship (because apparently girls like that). But, it never felt very satisfying to me, like I was forced to pretend to be something I'm not. I never felt comfortable. I kept waiting for it to get better but it never did and eventually I had to end it. 

Alternatively, I've had a few relationships where I feel like maybe I've finally met a girl who can accept me and understand me fully, even it comes with some insecurities. So after getting off to a great start (~2 months), I start opening up emotionally, and the girls always react very negatively. It usually kills things, and it drags out for a little while longer but the initial attraction and love she felt for me never returns. 

So I'm stuck. The only way I can successfully have a long-term relationship is by pretending to be a perfect person with no issues, and as a result I will never truly love my partner or feel committed to her or fully enjoy the relationship. But, as a guy, I don't feel comfortable sharing this part of myself with family or friends, I need to be REALLY close to someone to do it. So what's the alternative? I guess I could get a therapist but I don't like the thought of that, and I don't want to spend money on it anyway.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Stay emotionally closed, end up with unfulfilling long-term relationship. Open up emotionally, end up with no relationship. How can I have it all?
