When an ex-girlfriend says she misses you but has a boyfriend, it can be tempting to think that she wants to restart the relationship. However, it's important to approach the situation with caution. Here are some potential reasons why an ex-girlfriend might say this:

1. She's feeling nostalgic: Sometimes, people miss their old relationships because they're remembering the good times. This doesn't necessarily mean that she wants to get back together with you - it could just be a moment of wistfulness.

2. She's not happy in her current relationship: If your ex-girlfriend is in a new relationship but still thinking about you, it could be a sign that she's not completely satisfied with her current situation. However, this doesn't mean that she's ready to leave her new boyfriend and start something with you.

3. She's trying to keep you on the hook: Unfortunately, some people use the "I miss you" line to keep their exes interested in them, even if they have no intention of getting back together. This can be unfair and hurtful.

If your ex-girlfriend says she misses you, you might want to ask her more about how she's feeling and what she really means by that. Just be careful not to read too much into her words - it's important to listen to her actions as well. And remember, you deserve someone who is fully committed to you and willing to leave the past behind.
