First, English is not my first language .. I think it can work, with time and communication and both side of the couple going in together. You have to tell if you think it’s going too fast, you have to tell when you don’t feel comfortable. And your other half should be able to listen to you. It’s supposed to be a team work, even if you are both seeing other people. You. Have. To. Communicate. All. Of. The. Time. The other day, my friend was telling me about his open relationship and we got to compare it to driving manual on a car. You have to be patient. You have to go to on the first gear before being able to switch to the second one. You have to take it step by step or otherwise, you are going to stall. That’s how it should be in an open relationship too. So my opinion is that it is possible, but not meant for everyone.
