I am realising I still haven't let go of the expectation to be loved by my family unconditionally

It should also indicate that there wasn't anything wrong with that expectation other than, putting expectations on people will almost always lead to disappointment. Disappointment leads to resentment, and resentment (can) lead/s to hatred and animosity.

I do the same. I know where I can get that unconditional love in my family and where I can not. I also have learned to give because it makes me feel like a good person and not so much for others to love me the same way. That's what I have learned about myself. I hope this helps.

If such experience happened to me, I would have became a monk long ago. Love & care of my parents stopped me from going on that path.

It’s sad that they don't because they should have 😐
