For me, I like to know exactly where I stand with people. I found myself inadvertently in a FWB’s relationship when I was about your age. I thought we were boyfriend/girlfriend and I was truly in love with the fellow. I had the stupid idea of assuming that we were a real couple. One day, when I was trying to have a deep/romantic conversation with him, he told me that he didn’t feel as strongly as I did and it would be best if we “cooled it” (his words). Turns out that he was having relations with another girl at the same time. For him, we could have continued on indefinitely if I had never expressed any needs or desires and that the times we got together would be decided by him and only him, he would have been fine with that. He never really lied to me, it was more of the sin of ommision and not being clear and direct with me from the get go.
I vowed to never get involved in a situation in which the “relationship” was not clearly defined. I don’t mean that relationships have to be rigid, they just have to be defined and both parties need to be in agreement with what the relationship is and what it isn’t, and where it’s headed. To do otherwise is just setting both people up for frustration and anger and somebody, the one who cares more about the other person, is almost 100% likely to get hurt.
People get hurt in defined relationships too, when one of the people’s feelings changes and decides to go out of the boundaries of the relationship, but if you have no definition then you have no real way of moving forth or participating fully in a fill in the blank—- because we don’t know what we have, or don’t have. I believe in freedom and all that stuff, but the idea of floating around in a nebulous void is just not for me. Even if it ends, you don’t know whether you are broken up or not, because supposedly there was never anything there, or was there???
At this point in my life, with all that I have learned, and all of the pitfalls I’ve fallen into,I would not consider having a sexual relationship with someone who didn’t consider me to be his exclusive girlfriend. But that’s just me. I spent too much of my youth trying to fit in with some un-attainable idea of how I should be or change or accept, for a guy. Now I’m pretty sure of what I want and if the other person doesn’t like what I’m offering, then so be it.
And since we do live in a society, nebulous undefined relationships make it un-comfortable and awkward for other people too. I’m not saying that you or anyone else should conform to what society expects, but imagine how it must be for a parent to not know whether his child has a boyfriend/girlfriend or just a quickie sex partner. It would be perfectly acceptable to invite a boyfriend or fiance or spouse over to the holiday dinner, but it would be pretty embarrasing to invite someone who is simply a sex buddy. I know it’s very different for you, because your own father does not accept any kind of relationship attachments for his children (which is a huge obstacle for you to overcome). The problem with your father, and the fact that you live with him is the biggest problem that you have right now, regardless of the FWB’s guy.
Same goes for weddings or family parties. Imagine working at a company and there is some type of function in which spouses/SO’s are invited. How is that going to work? Imagine someone else wanting to date you or the nebulous guy. How do you explain the situation? What happens at the hospital when one of you is in the emergency room? If you don’t have some type of defined relationship, you won’t be allowed in to see or make decisions for your person (as a lot of gay people have known for years, because they are not allowed to define their relationship in a legal way).
Even with your own friends, it can be very awkward if they have no idea what this person is to you. Maybe that’s their own fault, that it’s awkward, but you have to realize that we live in a society and certain expectations go along with certain relationships.
The most important thing is for you to define exactly what it is that you want, and then make a plan on how to achieve that in a way that will not damage you.
