Is it a toxic one?

Boyfriend doesn't understand me nor tries to

So talk to him and try figuring things out otherwise it will be difficult for you

I tried talking to him and making him understand my issues but he already said he doesn't care.

Talk about your expectations and how it makes you feel.

Told him. He says I am irritating and that I keep repeating the same things over n over. I feel so lonely that I feel like killing myself

Don’t get negative thoughts. Talk to him and if he doesn’t value your emotions than I am afraid he ain’t the right one

The primary thing is you mental health and everything else is temporary and secondary. If you'll try to keep someone into you forcibly it won't work . Set him free dude. You are going to meet many in your life. Why are you chasing him even, for worth or love?? If worth, then start self worthiness. Your worth depends upon how you worth yourself. And if for love then go to your parents and have an eye contact with them, I hope you'll definitely realize what's called real love in this world. How much you may hurt them they'll never show your act a mirror . They forgive and accept you for the real you. And you are begging someone for love ! Oh come on. You are a blessed girl with lovable parents and that's what we need.

I am not chasing him nor am I forcing anything upon him.
