How to cope with being single?

How do ppl do it. They stay calm and then one day they meet someone and boom, they r in a relationship and then marriage.

I go on dates, I’ve been in relationships but nothing seems to last. Most of the time, people don’t want to work out issues and leave after the honey moon phase.

How can I make peace with being single? I want to love myself and when it happens it happens.

I just miss small romantic gestures and always having that person. Life becomes so much easier knowing that person is there for me.
