A Cancer will know when they have finally found the one because they will feel appreciated by them.
You want to be around this person at all times, not simply out of obligation.
You feel as if this person is your life partner, partner in crime, and right hand man.

Oliver Sjöström
You are excited to see where life takes the both of you, as one, together.
It simply just feels right.
You finally can take a step back and breathe, knowing that everything happens for a reason.
They bring you a feeling of security, confidence, and happiness that youve never felt before.
No more faking it.
You will finally feel as if your efforts are being recognized, and appreciated at last.
Youre used to getting your way, running your love life, and having control over everything and anything.
They will finally show you what it means to truly be on a team.
You are finally able to let go and be yourself.
You are used to keeping people at a safe distance, never fully letting them in.
But, this person has entirely changed all that.
In the past, youve chosen to be carefree, nonchalant, and open about your relationship status.
You liked knowing that you had multiple options, not one particular one.
The possibilities were endless, but you still wound up feeling alone and lost.
But now, you feel like you actually want to commit to the relationship.
You want this person and only this person.
You have realized that in fact, the grass isnt always greener.
You will finally feel like your partner is on your side, instead of constantly working against you.
They can read you like a book, and often time without you even needing to say anything.
You stop trying to protect your heart from being broken and let this person inside.
This person will finally put an end to that cycle, and change it for good.
You will let this person in, and they will remain there.
This person will bring out your passionate, imaginative side that youve tucked away for so many years.
They will heighten your senses, wake you up, and show you everything youre destined for.
You will know when you know.
And this time, you surely know it is right.
