I love him but he doesn't love me and i don't know why

It’s easy to like someone without being sexually attracted to them. Maybe he thinks you are too fat, or too thin, or ugly, or too tall, or too short, or not very intelligent, or very intelligent and he can’t keep up, maybe he thinks you are nice but boring, or so involved with other activities that you don’t have enough time to spend on him, maybe you are too rich and it’s scared him off or too poor and he’s a bit of a freeloader. Maybe he just prefers someone else and he is putting all his efforts into chasing her, maybe he is gay but just hasn’t come out yet.

I’m sure there are plenty of other possible reasons. So why not just ask him after all he may just be shy or scared of rejection!

There can be a variety of reasons.. and some of them you cannot control or fix.

But, sometimes there is a reason that can be fixed; like perhaps he actually was interested in you and the two of you could not effectively communicate your feelings and love to the other... so he lost interest.

I recommend you get and read the book: The 5 Love Languages by Gary Chapman. There are teenage and elderly versions as well.

It works best if both read the book (if this is the reason). Note: each partner will likely read the book at a different pace. I've seen people read in in 1 day, and others take up to 3 weeks as they slowly progress though it. Allow for that difference (as long as they are working on it).

If they are not willing to read the book... then they were not for you anyway.

Note, this book explained most of the past dating failures that both me and my wife had -and showed us how to show that we love each other... and made our marriage work.

I wish you well with this...

There's not always an answer. Sometimes you just feel for someone as a friend, these things cannot be controlled.
I've met people myself I wished I could've felt romantically for but I just didn't and it had nothing to do with them.

Don't question it, just accept it, and move on with your life.

It may not be your fault. Maybe he's just not capable of those feelings. Or you aren't really a good match, then I don't think faking your personality is a good thing or even gonna work. You should just move on instead

It's called a friendship. Maybe he just wanted you guys to be friends. Sometimes in life things aren't always meant to be.

Well why did you break up?
