1. Fighting in public. You should probably wait until you’re in the privacy of your own home to settle your arguments. You don’t want to make your friends feel awkward by fighting in front of them — and you definitely don’t want to get your friends involved in the argument and ask them to take sides. It’s not their responsibility to figure out who is right. Your problems are between you and your partner. You need to learn how to come to compromises on your own.
2. Engaging in way too much PDA. It’s fine to give your partner a kiss here and there or to hold hands with them beneath the dinner table. However, if you’re out with a group of friends, you don’t want to make them uncomfortable by initiating a full-on makeout session. Your friends don’t want to watch you get turned on. They don’t want to be forced to imagine what you look like in the bedroom together. Do them a favor and save your most intense kisses for when you get home.
3. Acting like you’re the only two people in the room. You might feel more comfortable with your partner than anyone else around you. You might have more to say to them and more inside jokes to share. However, if you wanted it to be just the two of you, you could’ve gone on a date by yourself. If you’re at a party or a dinner with friends, try to mingle. Don’t isolate yourself. Don’t act like everyone else is invisible to you. Don’t ignore what your other friends are saying because you’re too busy having a private conversation with your partner.
4. Talking nonstop about your newest milestone. Even though you might be excited about moving in together or planning your wedding or trying for a baby, your friends want to talk about other topics, too. You’re allowed to get excited about the milestone you’ve hit. You’re allowed to celebrate alongside the people who are the most important to you. Just remember your friends have lives, too. They have things they want to share, too. You don’t want every conversation to center around your relationship, even if that’s the only thing you’ve been thinking about lately.
5. Rehashing private moments. Your friends probably don’t want to hear too many details about your sex life when you’re both sitting right there. They probably don’t want to hear about your recent arguments, either. It can get a little awkward. It can make it tricky for them to respond. To put it bluntly, there are some things that should be kept between you and your partner.
6. Playing matchmaker. You don’t have to set up your friends with your partner’s friends. You don’t have to help them find love. They might be perfectly happy on their own. You can’t assume they want a partner (or that you’re an expert on love now) simply because you’re in a happy relationship. They’ll stay out of your relationship and you can stay out of theirs. That way, things won’t get messy.
