Sorry, but I have to say I disagree with your opinion regarding Finchel. No relationships are perfect - not even the "perfect" ones. Couples may have different dreams that might not be immediately reconcilable with one another's, but that's OKAY. What's important is support. For example, I recently entered a relationship that I KNOW is going to be long distance for a very long time, because I'm going to New York for school and he has a good, solid job on the other side of the continent. That doesn't mean we don't support each other, it doesn't mean we're choosing our dreams over each other. It means we're responsible members of a loving relationship who understand that each of us had things we wanted to accomplish before this all started. We recognize that if we don't complete what it is we set out to do, we will end up with a lot of resentment and hurt. We understand that, if we truly love each other, we have the rest of our lives together and the upcoming distance is but a small price to pay for complete fulfilment. We tell each other every day how proud we are of the decisions the other has made, and we mean it with all of our hearts. We're 20. Finn and Rachel are only in high school! If they have the foresight to comprehend this idea, I say good on them. Distance shouldn't, in my opinion, be a reason to discontinue your commitment to someone you care for, but if it IS, I congratulate anyone who will remain in a relationship they believe in for as long as they can before the distance separates them - I'm sure that's extremely hard.

As for the "toxicity" of the relationship, I'm not quite sure what you mean. They have misunderstandings, they have disagreements, yes, but doesn't any couple? Yes, they've both done questionable things with regards to the relationship (though if you think the vegan meat thing was one of them, I have to say... it's a comedy and you need to relax), but any time it's caused trouble, they've both learned and grown from the experience. That's what a young relationship is. It's testing the waters, it's getting your feet wet, it's learning how to tread in furious waters. Rachel had never been in a relationship before Finn, and Finn had only yet experienced the tyranny of Quinn. Neither of them was exactly an expert, and I think they've done a remarkable job thusfar of sprouting their wings.

Neither Finn or Rachel has missed opportunities because of their relationship. If anything, they've been there for each other and offered relentless support. That being said, all relationships require compromise, and it's entirely unrealistic and unfair to presume that they will never be made in this one.

Short of Tina and Mike, I think Finchel are the healthiest couple on that show. They convey a caricatured approach to a real high school romance, and there is nothing wrong with that. Consider the alternatives. St. Berry - the relationship that was wholly guided by the manipulations of Rachel's birth mother and then destroyed with no warning by Jesse, who chose Nationals over Rachel. Puckleberry? Just, no. And what about Finn? Should he go back to Quinn, who wanted to use him for a title? Who sees a future with him as bland and unexciting, as she explained to Rachel last season before Sectionals? Who LIED to him about losing her virginity to Puck and dragged him through 6 months of living hell as she pretended he was the father? No! The only other option I see is the two of them being single, and that's obviously not what they want. Sure, maybe their relationship is frivolous, but what romance is free of frivolity? Sometimes you have to do the "wrong" thing FOR the right thing.

Finn and Rachel are good for each other. Rachel believes in Finn, believes he's talented and more than just a guy who's good with his hands, and that's not just because she wants him to go to NYADA. She's never pestered him to try to get in there, she's only begged him to see himself how she does - with potential; not necessarily for Broadway or anything she might be interested in, just... with the potential to see himself as more than some guy who only DESERVES to live out his life in Lima. If that's what he chooses, so be it. She just wants to see him know that he has a choice, and I think that's beautiful. As for Finn, he tames Rachel's virulent (and sometimes harmful) ambition, almost in perfect synch with her ability to pull it out of him. They complement each other, and that's very rare.

In short, I think this fandom has gotten a little alarmist regarding the Finchel pairing. I think people have let their imaginary ideal situations get carried away and have then applied them to a show whose PURPOSE is to prove that beauty comes from situations that are NOT ideal. I think a lot of people either missed the point or let their own contradictory ship get in the way of objectivity.
