My girlfriend said please don't send text messages in the future.

Calm down and don't worry, because now, the more words you send, the more disgusted the other person will be. Wechat can't replace the telephone, because many women are imaginative (very touching) and often stretch their semantics and distort their original intention (this is the case in my family, not all). Better say it in person. Women are emotional and show sincerity when they meet.
