I have no time to reply to my girlfriend. I'm too busy at work. How to tell your girlfriend? How to explain to your girlfriend?

I have no time to work. I'm too busy. As long as you talk to your girlfriend, he will understand. I am really busy. I'm really tired and hard. Please understand me. I didn't reply to your message. Don't be angry with me. I didn't mean not to reply to you. I really have you in my heart. As long as you talk to him well, he will forgive you.
