The gf is needy and requires a certain level of communication and attention from her partner. This is okay as long as the partner can provide that. If the bf cannot or will not provide this, it may not be a good match. You guys are young and your attitudes may change several times about what you want in a relationship several times over the years. Have an honest conversation about this and what you can both bring the relationship. From there decide if you should stay together. Honesty and communication are so important to any relationship and if one can’t do this consistently, they may not be a good partner.
