I have been married for 15 years with two daughters . not a very happy marriage. Have met and fallen in love?

I have met the person I loved twenty years earlier to discover we love each other even more . Both are married though not so happy in our marriages but willing to go the extra mile to continue our marriages for the sake of our kids but we really understand and love each other purely and respect each others space and private lives. Should we stop meeting

Am glad unlike others, both of you have decided to respect each others private space. I guess now the relationship would be more as friends rather lovers.
I think you both should discuss this issue with your current partners and find out their thoughts and arrive at a amicable solution.
