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

You just have to feel like you can be completely honest and open with this person without judgement, that you can share your feelings. It's when you love spending time with them and can't stand being apart so in my case you're both messaging back and forth constantly when you're not in a call or holding hands in real life. You'll know without a doubt if he/she is the 'one'. (◕‿◕✿)

It will be shown over time and under the right conditions. The gut feeling may scream "they are the one" now, but give it some time and see. For example, I thought I was in the right relationship (10+ years, since middle school) but once she moved in with me, things started to fall apart. We tried to make it work, but, within a year, we found out that even though we absolutely loved each other, we simply could not live together due to certain personal circumstances. There is no definitive answer, since people change and so do feelings and situations. It's best to roll with the flow, recognize any potential issues that may harm the relationship, and communicate that with them. If the issues can be solved, you're good, but if they can't, then it may be a sign.

Instead of wasting time on questions like that, why don't you just make sure your current relationship goes well. Then you won't have to worry.

Relationships have several different stages, so you never really know right off the bat if someone is right for you. Someone may click with you upon the first date, and you may be compatible on a surface level, only to find out as you enter a new stage that she has certain emotional turmoils that you are ill equipped and unprepared to deal with. (Or vice versa). Then say you do stay together and you've gotten used to it. You've made it past the preliminaries, but you both have those certain habits that really grate on your patience, so you both start trying to subtly change one another. Let's say you make it past that. (Actually no one really does, but they find ways to live with it.) You're a few years in the relationship, and everything has gotten boring, predictable, and repetitive, and regardless of how many times one of you does that new and exciting thing, you now know each other way too well. You start to crave new flavors. You look at the partners your friends have in their lives. And on it goes... But you're still together, and then you fall in love all over again with the same person. And suddenly, you're reminded of the way you felt about him/her when you first got together. But it's different now, as you two have grown. You are now two very different people than you were at the start. And the cycle circles to completion, only to spur forward anew. So I think the only real way to know if someone is right for you is to have been around the cycle of love more than once, and to be confident that you are both willing to make it through the next few winters together. So basically, don't think about whether someone is the right person for you. Just appreciate them as if they could be.

When you don't want to leave the relationship and are committed to working on making it work, and when the other person is doing the same.

When seeing her face doesnt annoy you. When you actually want to go home to her. Once those things change, you should see whats happening to cause you to feel badly towards her. Either figure out a way to fix it, or leave. But communication is the one thing you should always have. Its like relationship #1. The minute you start holding things in, you're killing yourself in the future.
