Remember this: “It’s not always about you.” It’s a natural tendency to take things personally- someone’s bad mood, or not paying attention to you, or not calling, etc. But most times when we see people acting shy/aloof/crabby or mean - it has nothing to do with us and everything to do with them, and what they’re experiencing.
Try (a) not to take things personally and (b) to have compassion for people, who are all going through something.
Don’t Just “go along for the ride” in your relationships. Be clear about your intentions and act accordingly. It’s part of being a man. A GOOD man. Sometimes you just need to have a talk and make sure you’re both on the same page. It won’t $@!#% you!
When you begin dating it’s all butterflies and moonbeams. Eventually you’re going to do or say something that hurts the other person and vice versa. For that matter, eventually you’ll disagree about something. It’s VERY important to consider how they handle it. Nobody is perfect, it may not be pretty but it had better be civil. If not, don’t think for a second that they will change. Get outta there.
Default to "nice guy." Meaning it should require something significant for you NOT to be nice. Give people the benefit of the doubt. Cut them (and yourself) some slack. Life is hard. We're all in this together.
