Driving over 300 miles just to see someone for few minutes

Is it stupid from me that I want to drive over 300 miles (500km) to see my kinda-boyfriend? He flies to Paris and then from there 2 weeks later to Israel via Frankfurt Airport. He has a layover of 2.5h. Arrives at 5pm (maybe even 4:45pm) and his next flight is at 7pm. Both in the same Terminal (Terminal 1) but different gates (A40 and C13). Is he able to manage to go out of the security zone to see me on the other side with that time without missing his flight?
I haven't seen him in 7 months, met him in the US and we dated and then got together (only for 3 months because I had to leave). This is our only possiblity to see each other face to face, I'm not planning to go to the US for some time and he might be able to see him next year but till then who knows what happens (even thought I don't wanna lose him).
​So do you think it's possible for him to  go out and see me without missing his flight and do you think I'm silly because I'm planning to drive that long ride (300 miles each drive) just to see him possibly for only few minutes?
