I tell you something, might be hard but some girls need strong medicines!
I guess now you have plently of time to daydream.
You don't have to work, just be full time mother.
Think about it, that if every day you have to get up at 5 am, bring kid to kindergarten, try
to get into office before 8 am, then your boss give you deadline assignment every two days.
Then 17 hr, you have to fight the traffic, pick you your kid, cook for you family and parent-
in-law, clean up after dinner, bring kid to bath, bring him to bed.. bla-bla-bla..
You will daydream less.

If your husband works alone to feed you and kid.
If he brings money home for food, rent, school fee, holiday..
and leave you enough time to log in Pantip, you should appreciate it.

You should start from this new year, plan something more for your husband and kid.
Cook some food, play with kid.. find any activities.

I don't want to shatter your dream.
But if you told your ex boyfriend tomorrow that you still love him, you would leave your husband and kid
for him,  I'm sure he would run a mile away. Do you think he would love enough to take you back?
I don't think so, consider your current situation.

You should be happy with your present, and be extra nice to your husband and kid.
Don't do anything that make your husband and kid stop to respect you.
Moreover, you should respect yourself first.

I know my comment is not pinky-rosa, like I said some people need strong medicines!
