Time will dull all wounds

A friend told me that time will heal all wounds.

Another told me that's not true. Time will dull all wounds. The wounds will always be there.

This can only be very true for my case.

She was my first gf. She stole my first kiss. She will always have that special place in my heart. If I get another girl friend, I wont' be able to love that gf 100% cause at least 1% will always be with her.

It's not fair. To anyone I eventually be with. But I cannot, I will not go back to her. I have decided as much. So help me, if the time comes, I can be strong.
