Essentially exactly the same suggestions as USA-Alice made - so I'll chop out those parts

[This entry was very good and very easy to understand. A native English speaker would understand exactly what you were saying if they read this. Most of the clean-up I did was on sentence structure, trying to make your entry flow better. Remember to put spaces after a comma, period, question mark, or exclamation mark, as I have done here. When you said "a sad thing in life," saying "in life," is redundant. Letting go is obviously a thing in life, so it sounds a bit awkward when you say it. To answer the question in the entry, yes I have loved someone very deeply but ended up engaged to another person. We both loved each other very deeply, but at the time there were too many things preventing us from being together, and his love for me did not endure it. I love someone else now, someone that I could never imagine leaving, who feels the same way about me. I think that is true love-- when one person will do whatever their partner asks because they completely trust their partner and know they would do the same for them if they asked.]
