I hate how bitter and jealous I am.
That sounds difficult. Why are you so bitter?
Because I've been with my boyfriend a long time and I'm tired of waiting for him to do romantic things like give me a kiss or tell me I'm beautiful, or just hold my hand.
If you are not getting emotional fulfillment from your relationship, you should have an honest discussion with your partner. They might not know what you want. Or they might have different ideas about relationships and you might discover you're not compatible and need to break up.
I'm being honest right now. Why should I have to be the one to bring it up?
You should bring it up because you are the one who is upset by what's going on. If your boyfriend thinks his behavior is acceptable, he won't mention anything about it. I know it's difficult, but you need to talk through this problem with your boyfriend.
