Hi Jey,
Avoid engaging in behavior that would make her jealous or angry.
If she is currently angry with you because you take a long time to reply to her text messages, give it a couple of days before reaching out to her.
When you do, let her know that you have missed chatting with her the last couple of days and make sure that you use humor to make her laugh.
She would have probably cooled off by this point and would be more receptive to interacting with you.
However, from this point on, you should ensure that you respond to her text messages sooner so that you don’t give her reason to get angry with you again.
