At times, grownup Scorpios can get overwhelmed with how much they care, then unconsciously suppress their feelings. Emotions cannot be stashed. Eventually the tears or backed up anger will come out. Stay current with your love. It is okay to cry when you re happy.
Dads especially feel funny at how much they love their kids.
It's a strange problem to feel so much that you hold it in. Caring, loving and needing contact are good things. You re a great parent because you can sense what your children are feeling before they can. You re attentive and at worst can be overbearing. Be willing to allow your child risk.
