Feeling ...blank?

Today I've been lounging besides a 45 min run at the gym where I did hit a new milestone of 2.35 miles and a high level on the treadmill but that's for my self esteem and another time.
Recently found another girl to talk to. Talked to her for 2-3 months and again she disappeared off the face of the earth again. So again I am .... out and about looking maybe? I am not really looking I am just tired .... the people who come to me seem to want one thing. Something I don't want. The ones I start pursuing and finding other things in common and maybe even date do the same thing. They fall off the face of the earth. 
 
Now I'm feeling really.... blank I don't know where to go from now. I like someone.. but she's in a complicated relationship and I know better. So we are friends and I am not doing anything to start even constitute cheating because I know how serious she is with her gf. They were engaged before she went to boot camp and things got complicated. But other than that I have no where to go from here... Where do I go?.... what do I do? ..... this sucks...
