Does he/she love me or someone else?

Communication is key. There may be signs that may show you lack of affection, but the best way to know is to ask them straight out.

this is complicated. the best you could do is talk with him/her and its normal to be scared about it. but, you know, if you never shoot you'll never know (:

This is just that one question everybody wishes there was an easy solution to, but doesn't have one. Love is a complex emotion that varies from person to person . wanna know if he/she loves you, but afraid to ask? Well, then the best way to figure it out is to observe as much as possible. As much as you can, observe. Look at body language, and what they say to you, also how often they wanna hang out and be with you. Now, everyone is different and I've known people who try to hang out lesser with the people theyre in love with! Remember not one size fits all :)

That's a question that should not even pop up. You would know not when they tell you but by their actions.

Love is emotion and can't be judged in just a second. It needs evaluation but many a times negative thinking effects on our understanding badly.

That's a question that you're going to have to ask yourself, if you have doubts then perhaps you should consider asking the person you're wondering about. However, this is a choice you're going to have to make on your own.

What does your heart and intuition say? If you already have these questions and feelings maybe you should question what is leading to this?

The best to know if he/she loves somebody else, is to ask them. Then at least you know where you stand with that person.

If you are ever unsure if your partner loves you then the best thing to do is talk to him/her about it,

well it depends on what happens if he acts different then he/she does but if he is not then he loves you
