She, Her, Hers

Is she in happy relationship with herself or she wants to be emotionally dependent on someone? 

Being independent doesn't mean she doesn't need someone to depend on. She loves being existed with herself, no debate. But you know what's better than alcohol? Someone who listens to her, someone her age, because sharing her life would really help. Will she find someone special to talk to? We'll see.

Does she really love this person or she is choosing him out of her loneliness?

Being with someone isn't a guarantee she will fucking get out from her loneliness. It's not love either. In this moment she is trying to feel, to love, to being existed with someone else. Kindness isn't flirting, attention isn't caring, affection isn't lust, and attracted isn't always love. It's never gonna be her fault for being such a nice person to anyone, to him. She is scared as fuck to face someone. You'd better treat her like you want to be treated, love her as hard as she tries. Reread this paragraph without 'not', hope you'll find something different, something she wants to.

Is he the right person for her in relation to her needs, desires, life style, thoughts, and compatibility?

She can't let that thought ruin what she would have ever again. Those thoughts snatched her hopes thousand times. Those thoughts also ate her mind every single minute and turn the last pieces of her heart off bit by bit. She could adjust her needs, desires, life style, thoughts, and compatibility. If she couldn't, she must be figure something out. She just needs someone she can pour her soul, lean her shoulder, and cuddle to release her burnout.
