i thought that too but things relationship wise aint worked out since then a friend of my sister said something that really made me think about everything "i feel we can only really love once and once that's over again you wont love another"
I kind of get that T.T
Love is like virginity once you I've it away, you can never get it back
You'll never forget the love you had for someone, probably never lose the feelings for that person either.
The important thing is that you were able to feel that way at all. You can make new love with someone new, the fact that you feel sad is proof that you can feel happy too. We're molded by our experiences, losing something like that just means you can appreciate what love is.
Don't worry about never finding love again, because you will love again.
