To put it bluntly, you call it "eating what's in the bowl and watching what's in the pot"; This mountain looks higher than that one!

When you don't have a girlfriend, your current companion spent that lonely and difficult time with you, giving you spiritual comfort; Now that you have a new candidate, you are restless and in spirit again.

love should be faithful and single-minded. Be kind, don't forget your roots, don't change your mind. Be a man and do things to live up to your conscience.

Advise the landlord to cherish his current girlfriend. As you said, she is still devoted to you and always loves you so much. And you may not be able to catch the person you like, which means she may not fall in love with a person who is not expert in emotion.

give up what you have and pursue the unknown. At this rate, you will be empty-handed sooner or later.

words may be unpleasant, but you can ignore them if you mind.

take care of yourself!
