1. Lower your expectations
Unlike regular casual encounters dating relationships, FWB relationships are two people who come together because of sexual attraction and have nothing to do with feelings. So you can't look at NSA relationships from a conventional perspective. If you want to harvest happiness, comfort and commitment in this relationship, you will only be disappointed in the end. So, don't yearn for the two of you to be stable and long-term together, and don't yearn for any promises he will make for you. Before jumping into a FWB relationship, you should think about what you really want. If you can't get what you want from this relationship, you'd better stay away from it.
2. You can leave freely
One advantage of NSA relationships over traditional dating is that when you are not satisfied with your current status or have new options, you are free to leave. You don't need any psychological pressure, you don't need to be morally condemned, you don't hurt anyone, because your FWB just wants to have sex like you. So if you want to look for new opportunities, you can leave because your relationship has no strings attached. Go somewhere better and more interesting. This place is no longer suitable for you.
3. Causing his jealousy
Show him that your new colleagues are interested in your work and take action against you. Cause your friend's jealousy and make him feel insecure and uneasy so that he knows he's being challenged. Make him feel that you are very popular, and many people value you very much. This allows you to enjoy the excitement of pursuit. Inject some enthusiasm and passion into your dying NASA relationship. Maybe he will criticize you more severely tonight, or tell you who is the master. Or, if something on your body causes some anxiety, if he cares about you, it will certainly affect him. It's the best way to see if he really cares about you and if there's anything worth pursuing.
4. Avoid excessive attachment
Keep your distance. Don't be too sticky. Get to know new friends and find other friends. He may feel that if he's just not interested, he'll follow the crowd. Don't let him be your only choice. It's the best and easiest way to separate from him and forget him. Don't spend all your time and attention with a special friend when dealing with other people. What's so special about him? He's easy to replace. If you concentrate all your attention on him, you will never know what you have missed.
5. Try something new
If you've been in the same place since the first meeting, it's sooner or later that the flame will go out completely. It's always a good idea to explore different ideas. You never know how much you'll like them. Keep trying something exciting; something you've never done before, and you'll be surprised by the sudden surge of enthusiasm from your FWB partner.
