Is it normal that i carnt get emotionally attached

It's better to hold your love for someone that deserves it rather than throwing it around to anyone that looks your way. It was same for me, I just dated for fun. Until at 20, I met my girlfriend, who I knew was someone special. But, even still it took a while for me to say "I love you"

That's normal, when you set your standards to those around you to love than you will never feel like it is good enough. They obviously weren't right for you, and you will know when it's real. It's not that you can't ever feel it, you are just young and have never found it yet. Keep looking! :)

Attachment takes time, you have to do new things and create experiences together. Lust at first sight is usually a good sign, but if you'd like a lasting relationship slow it up & take things step by step.

Nothing wrong with setting the bar high - what I'm hearing from you is that you wont settle, alot of people do.....and jusitfy that by calling it 'love' - it's not, never do that

Maybe because they are not right for you.

Maybe because they cheated on you?
