I'm not a professional but there is a 15yr age gap between me and my partner. It can work but there are issues that have to be worked out first. The question of children is something should be addressed as should other life questions. It's also important to discuss whether you will be able to deal with negative attention from other people maybe even family members. There are many things to consider if you intend to become a committed couple. But most of all go into any relationship with your eyes open and willing to compromise. It can work, but it's not for the faint hearted. But then again no relationship is a bed of roses
