My girlfriend consistently avoids all forms of intimacy or romantic tension. Whenever I bring up romance, she changes the subject or says she needs "more time," despite having plenty of relationship experience in the past. We function exactly like best friends, but she refuses to acknowledge that the romantic spark is missing. Is it possible she loves me but has zero romantic attraction to me? Why would a woman stay in a relationship if she has no desire to be romantic? Is she just keeping me around for safety and stability?
