<human>: Can you summarize the given text in a few sentences?

I met this guy at a bar and we ended up talking instead of drinking/dancing. After a three hour long conversation he asked me out on a date. After a few dates, I knew that he was the one. He wanted to wait 15 dates before anything physical, he was bragging to his friends about me. I never usually like a guy romantically, but he really just blew my mind

We had a great time seeing each other for three weeks then he just stopped taking my calls/replying to my text. For the next three weeks, he only texted when he was drunk with things like "there are no other girl except you, I just become dumb when relationships come at me" or things like "I can't stop thinking about you". But when I replied, he would never respond back. So I started dating other guys and he texts me on Valentines day and tells me that he can't stop thinking about me.

I was JUST starting to get over him but I knew that I still liked him a lot. So when we talked that night, he told me that there are no other girl but me and he couldn't stop thinking about me. But he is afraid of commitments and he doesn't want to put me through any difficult situations (he is afraid that i will have a really hard time waiting for him)

*he is in the navy and he will be off to afghanistan in the front lines for eleven months in august as a corpsman.

We have been seeing each other again but all of my friends hate him because he has been to jail due to DUI/assault but I think he is a changed person. I just don't know what to do since I really like him but everyone is telling me that I should just walk away now. 
Logically, I can understand where my friends are coming from.. but can someone offer an insight please?
<bot>: I like this guy but everyone tells me that he is not good enough for me. feeling wise i want to be with him. logic wise i don't know if its the smartest idea..
