Be your own person. Having your own interests, hobbies and friends is what makes you unique. If you feel you're ready for a long-term relationship with a special person, ask for a commitment. If your partner doesn't want a committed relationship with you, tell your partner you are going to date other people. THEN DO IT .
Actions speak louder than words.
Your partner may rethink the situation. If not, you then have the option to begin making other plans, which may or may not include that person. Don't expect too much. Keep the relationship balanced. Take your time.
