Hi TS. I've went on several dates with the same type of girls and let me be the first to tell you that she is just not worth it. When a woman likes you, she will be thinking about you a lot. She won't wait days to read your message and reply to you. Since you're looking for a wife, you're essentially looking for someone who wants companionship. This ISTP girl you're dating is simply using you to make her feel good about herself as you're always eager to give her attention. The moment she meets somebody who makes her heart skip a beat, she will be ghosting you PERMANENTLY.

Your attention and love deserve to go to someone who cherishes it. Don't waste your time with selfish people who are not going to give the same amount of effort as you.
