Jackie,

Consider the following questions-

1) do you want a romantic relationship with him?
2) can you stay just friends with him? (minus the kissing and cuddling)

If the answer is no to both, then limit contact with this person for your well-being and his. Sometimes the kinder way is the harder way.

Regarding him reminding you of your mom, all I can say is that you aren’t a child anymore. Make your choices. Figure your life out for your sake.

I hope the other posters will have more enriching insights.

Regards,
Nina
