General question about love...

My story:

I met my first love 4 years ago we were best friends and lovers. Long story short we never worked out and we both moved on however I genuinely loved him so badly and still to this day can still stay there is lover there.... I now have a partner of nearly 3 years who I love to bits and we have 2 beautiful boys together...but is it normal for those little feelings for my first love to be there still? Do you ever actually get over your first love?
