<human>: Right now, the most important issue in my life is my lack of love, and I don't want it to be this way.

Background: I've had very limited success with women over the years, two one-month-long relationships and a smattering of flings being about it. The last relationship, while brief, was the closest I've ever come to love, and the girl left me in a really shitty way without giving me closure.

So now I find myself dissatisfied with life. I love my job, I have interests and hobbies, and I have great friends and family, but I always feel this ache in the pit of my chest that I believe can only be fixed by love. I'm a romantic at heart and believe that love will one day come to me naturally, but until then, I'm anxious and melancholy. I waste inordinate time obsessing with online dating, and I social network stalk my ex (I don't want her back, but more like I want her to want me back so I can regain some agency in the issue... I know it's fucked up).

I feel like I've done all the things people always say to be single and happy. I'm active, socially and mentally, and I like myself. God knows I'm used to the single life. However, it seems to me, and its been this way for a long time, that love is the only way I'll ever be happy. Its by far the highest goal I have in life. I think it would be more productive to weigh things differently in my life, but I just can't.

Can you summarize the given text in a few sentences?
<bot>: I feel like my love life has more control over me than I over it. Finding love is far too important to me. How do I stop obsessing over relationships and become comfortable being single?
