We had fun together...but I was going trhough alot...so eventually i stopped answering his calls and ignored him. Wel about 6months to a r later i started thinking about him ALOT ALOT. Well as coincidence..i saw him at a restaruant...when we sawe eachother..i walked by quickly.smiled and waved..i was so shocked. I didnt know what to do. Well the waitress sat us next to them. I saw a woman with him..me and him kept staring at achother.Well inoticed she was pregnant. I was mortified. But i let it go. then about another yr later..this past feb/march. I was thinking about him AGAIN! very strongly. I was even having dreams about him. Well i saw him AGIAN! this time..we got to talk to eachother.He got my number.We talked over the phone. I went to austin with him. we had a very special time together,
