In qq, I read the comments of my girlfriend and ex-boyfriend, which are full of love words with my ex-boyfriend, although he has said those words in our communication.

First of all, confidence is the key. Now that you have read it, don't let it affect the feelings of both sides. Adjust your mentality. Perhaps, you can't compare with his predecessor's excellent humor (wild guess), but if I don't think you should doubt it, not only will the problem not be solved, but your feelings will plummet. As a man, you should look at yourself and create advantages for yourself. It's definitely not good to ask her directly, because there is a great chance of quarreling and it may get out of hand. You should learn to change yourself a little. Relationships don't last for a day or two. I wish you happiness.
