He is my nephew, he & my BFs DD chose to begin dating during a trip to WDW. We were shocked because we saw it as a family relationship. We are not drama seeking people but that doesn't mean drama can't find its way into your life. This is what we were faced with, each of us looking at 2 kids we love making what we considered a big mistake. We tried, in the most sensitive way possible, to explain the bigger picture without shaming them. It was horrible.I'm only up to pg 5 so far in reading up on this thread, but the whole thing with your BF's daughter and your nephew/son/whatever you call him dating her falls into the realm of Jerry Springer talk show material.
Way too much drama.
If you really were satisfied and happy with the status quo, then you wouldn't be saying that you're unhappy with the current state of affairs. You are not looking to get married to your BF and that's totally fine. But you want to be given the same respect as a spouse would receive. And your BF is, frankly, treating you like crap. Only he's wrapped it in nice wrapping paper and disguised it so you will ignore and hopefully forget that he's treating you like an 18 year long booty call.
Actions speak louder than words. If he really considers you family like he SAYS he does, then you wouldn't be excluded by him to every family event. And being in a relationship like that for 18 long years? Something rotten is in the state of Denmark. Something isn't right here.
You are wasting your time with this guy. You deserve better treatment. But you are certainly free to continue if you want in a relationship in which your boyfriend treats you well and says nice things to you in private, but in front of others, won't even be in the same room as you...and excludes you and pretends in front of his family like you don't exist. You need to ask yourself why you are willing to be treated that way. Why are you willing to be treated like that by a person who claims to care about you so much?
Are there levels of respect? More for a wife than a girlfriend? To me respect is respect. I do realize something is off between me & DBF which is why I sought help from the DISers. I don't feel like an 18 year long booty call, we do go a little deeper than that.
