Well, as Magdlyn pointed out, being the new person that joins an established couple is considered one of the hardest poly relationships to manage. Of course, it depends on the individuals, but there are common patterns you need to watch out for. Right now, everything will seem rosy, as you’ll probably all have New Relationship Energy (NRE). This feels wonderful, but will gradually change over time. What is important is to be really good at communicating and clear about your needs and boundaries.
Things to watch out for include:
- Different relationships. You’re not dating a unit, you’re dating two individual people. This makes three relationships. You + husband. You + wife. Wife + husband. What happens if one relationship works, but another doesn’t? How do you allocate time to each of your relationships? Are you expected to act always as a triad?
- Couples privilege. Some couples have their own agreements about prioritising their ‘primary’ relationship that are not fair to the third person. This can extend into unfair allocations of time, finance, other resources, where the primary couple assumes they have priority, and that you, as the secondary, will be willing to sacrifice your needs for the primary dyad. This so rarely works well for the secondary that you’ll hear phrases like ‘unicorn’ and ‘unicorn hunters,’ because it is so rare that someone wants to play this part. Look them up and read around the subject. Remember your feelings and needs are just as important as the husband’s and as the wife’s.
- Couples veto. Some couples have a prior agreement that one can veto the other’s relationship if they start to get uncomfortable. So, for example, if wife/husband gets jealous that you are closer to the other, they can say when it ends. This is not fair and not healthy polyamory.
- Sex. Do you have sex with each of them separately, or are you only ‘allowed’ to have sex with both of them, but they can have sex with each other? Are you ’allowed’ to have other sexual partners outside the triad (subject to STI checks)? In other words, do they try to exert control? What happens if you want more sex with one than another, if you don’t want to always be three in a bed?
- Sticking plaster. Does the married couple have a healthy relationship that genuinely seeks greater expression through polyamory? Unfortunately, some couples get into poly because they have problems in their marriage, and think that adding a third person is the solution (a sticking plaster that holds them together). If they weren’t good at their main relationship, then all hell may break loose when they try to navigate the two extra relationships they have with you-- once the NRE wears off.
These are just some of the common pitfalls. As this is your first time, be sure to educate yourself and don’t just rely on what the couple say. They may have lots of experience and be great, or they may be new to this too, and not necessarily well-informed. This forum has lots of links to great resources. Discuss feelings and issues as they emerge, even if it feels a bit awkward to start with. Be clear about your needs and boundaries, and if they are seen as ‘second-class,’ be prepared to say, ‘This doesn’t work for me any more,’ and move onto another relationship that does.
But it may also work really well. Just because triads are harder to navigate doesn’t mean they never work. Whatever happens, this will be a truly exciting, deep-learning adventure on your lifelong path of fully becoming yourself.
Having confidence that you’re in a truly healthy
pair of relationships and you’re happy will give you more confidence to tell friends and family-- when and if the right time comes. They may or may not accept your desire to be polyamorous, but you will, by then, have developed more vocabulary and confidence to be clear about who you are.
Good luck and enjoy the journey!
