How do you know when you're in the right relationship?

I'm sure a lot of you have been asked this question or maybe you haven't but there is a big question that has been going around in my head. What is the right relationship for an otaku or just for a normal guy? I've been wondering this for a while and truly wanted to know.

You just know. Everyone has different things that need to be seen in order to know. For me, it was when I knew how comfortable I was, how unquestioning her love (and mine) is, how giving she is, how she ALWAYS wants me, how even in silence we love being around eachother, we both have a lot of the same outlooks on life, when she said "I do"(We're married, so there's that. ) and she just feels like the missing piece I was looking for Like I said, when you know, you just know.

you just know. youll usually feel truly connected to that person, and like being with them more than everyone else lol. youll know. it does take time though.

You don't know. You'll probably never know. It could be 10 years later and they'll screw you over. You just have to give in to fate. Are you happy now? Do you foresee yourself being happy with them in the future? Do they seem considerate of you? Do they seem happy? That's about all you can really try to figure out.

Well, you don't know and anyone that tells you so is foolish. The reality is you and everyone else has no idea but they do have a feeling and chemical feeling that leads them to have a relationship for as long as that chemical keeps pumping in the head. So as long as both you and the other person feel the same about the relationship it should be enough to hold you together. There's a technical number that someone could and has made based on compatibility algorithms but I don't know the numbers and percents. You could also be the only one that feels the connection and the other one will just brush you off so the compatibility really needs to be there. You can always ask the person how they feel about the relationship and all. I doubt most people even find the perfect match and even if they did they still wouldn't know. I wish I was a time warping parallel universe jumping agent and that I could tell you the answer but I can't and this is all I got, which is the cold truth of reality.

The reason I ask this question is because I have been through a lot of relationship where the relationship seems nice on the surface or in my mind but there is a thing called a honeymoon phase or in a love trance where either the two are so happy together they can't see that something is wrong or one of the members of the relationship he's so in love with the other that he or she cannot understand what they are saying at that very moment.
