I agree with Bpcyclist. If this is an ongoing pattern of her being inconsiderate of your needs, self-absorbed and nasty at times; this is a red flag my friend. There is a difference between having an attitude because you have a headache, and having an attitude because you cannot control/no awareness of your emotional self. I love the saying “hurt people hurt people” because it shows us that a person cannot treat you any better than how they treat themselves. So if your girlfriend is a moody, prickly personality kinda person, she cannot give you the intimacy, warmth, soft cuddles and affection you desire. Perhaps you need to understand who she is and that will show you what she can and can’t offer you. From then on, you have a choice whether to accept her for who she is and what she can and can’t give you, or walk away and seek someone who can meet your core needs.

I hope all goes well!
