OP, you knew that this relationship had limits, you’ve said as much in your posts. You just wanted more time together to enjoy before it became sabotaged, ans that is okay. Maybe he was worried of loving you too much and not being able to manage the conflict with his family if *he* could not break it off or deal with the family rejection.
Be thankful for the good time you shared and had together, make a note of the qualities you will value in another partner, and remember you never date people that are worse than before; each one is better than the last.
Signed,
Someone happily in love with a lifetime partner that is young, never married, and in love with a divorcee and her children. Also our families love and respect both of us. His family brings gifts foe me and the kids. Love is out there. Be thankful for the time, and prepare for the next adventure life brings.
