Make sure your girlfriend is LES first. If so, those words on WeChat can be understood as love. So there are two possibilities for her to keep in touch now. 1 Love your ex-girlfriend. She stayed with you because someone took care of her, and now there is no one around. In this way, it is more likely that the two will get back together. In tragedy 2, you don't love your ex-girlfriend, but it's hard to change the habit of liking someone for a long time, and you won't lose contact for a long time. At this rate, you will definitely be unhappy.
Therefore, the suggestion to the landlord is that if the girlfriend is a real LES, it is best to break up. Because she only loves the same sex, which will only make you more miserable. Ps: les friends around me broke up with men soon anyway.
Still wish the landlord happiness.
