What should I do if I find many ambiguous messages from strange girls on my boyfriend's mobile phone?

The relationship between men and women is very delicate. I feel that your boyfriend has shirked all the responsibilities and "promised not to talk to her again". What is guaranteed feels simple and far-fetched. Since there is nothing, why give them a guarantee? Maybe you are a little anxious or care too much about you. :)

Support the second floor! You should spend more time with your boyfriend and care about him!

Don't think about asking in person or beating around the bush, it will hurt your feelings. It's hard for any man to accept girls' distrust of himself (especially naive and self-respecting men).

Don't worry too much, just wait and see. This is a test of your love.

If you find that this man is really sorry for you, I strongly suggest you kick him away. This kind of man is absolutely unforgivable, otherwise it will always be himself who gets hurt! You know, there are still many good men in the world!
