<human>: Can you give me the gist of the text in a nutshell?

Okay I will try to keep this relatively short. (Which means I will probably rant).

In highschool, I was kind of a social outcast. I had a small group of ROTC friends, but other than that I didn't get along with most of my classmates. I had "dated" 3 girls but never really went on a date other than the military ball freshman year we stayed until after the meal and she didn't want to dance so I took her home and she went on ignoring me (sister's friend). The second girl (also a friend of my sister) made out with some random guy in front of the school within a week of us getting together, the third broke up with me the night before I was supposed to take her to her prom (I can "thank" my cousin for introducing me to her). After highschool I went into the navy and got a medical discharge not soon after. 2 days after getting back home I went on a date with a friend I had known since 8th grade. That was my first and I guess only real date, and that was almost 5 years ago. After a while the routine of class, work, WoW, gets pretty boring and I really wanted to meet someone I could hang out with. So despite my better judgment I made a profile on OKCupid. After a few weeks I started talking to a girl, turns out we had met before at her old job, I had flirted a bit and she wasn't interested. After talking for a few weeks I got really busy with class and work and couldn't check my messages for a few days. So when I logged on after getting off work late one night, I had a message from her with her phone number. So I figured what the hell text her (she had previously stated she didn't like talking on the phone). After about a week of this we decided to go out. We have had 2 dates now, and I am just not feeling a lasting (or any) connection. So given how I had pretty much 0 experience dating, I want to know how I can tell her I am not really feeling anything, but do it in a nice way?
<bot>: I am a noob at dating and I don't see a lasting relationship with the girl I am dating, how do I nicely tell her I am not feeling anything?
