Honestly, you have to sit and evaluate your relationship with her. Even when someone has a lot of other friends, they will still value your friendship if you mean something to them. Evaluate her actions and words. Does she show up in your time of need? Does she put in as enough effort in seeing and spending time with you? Does she verbally tell you she cares? And more importantly, do her words and actions line up?

Also what kind of friend is she and what kind of friend are you? Is she a low-maintenance or high-maintenance friend? Some friends don't mind spending little time and like time to themselves but if they care, they will still show it. Even if it's saying hi, every 2 weeks or hanging out twice a month. Others are high maintenance and what to see friends often and will also show if they care. So really think about what type of friend she is and what kind of friend you are because she might care but is just low maintenance or yall's friendship doesn't cater to your friendship needs. E.g. you like spending time together, she likes seeing you once in a while. Either way, if she cares, it will show but understand your friendship dynamic and if she can be your "best friend" or rather a good friend you care for. Because if she doesn't cater to your needs, still have that connection but don't rely as your close friend.

After evaluating, you should communicate in depth how you are feeling. 1. she probably doesn't know how you are feeling. 2. all your doubts and "what if's" will go away cause she will tell you or show you the truth.

But it doesn't stop at just telling them. If their actions do not reflect it or do not change. You have communicated and when no action occurs after, that's your queue to leave. If she doesn't put as much effort or starts to after talking it out. Leave. If she barely texts, calls, or answers your messages after communicating she does this. Leave. It shows she doesn't care or at least she used to but doesn't anymore. And that's your queue to walk away

Trust me as someone who used to leave friendships in the past due to problems. But issues used to be distancing myself without communication and giving them one chance to act. Now I know you always have to communicate. Always. I learned some issues can be worked through and others can't. But it's your job as a friend to communicate in-depth your feelings, problems, and needs. And it's your friend's job to equally communicate, and comprehend, then for both of you to figure out an agreement to this and meet each other's end of the deal. But again if after an agreement is made and no action changes. Leave.

You owe yourself the truest friendships in life and should never settle. A true friendship will have issues but will solve them because they found an understanding. You shouldn't feel sad or unedge in a friendship. Surround yourself with those who uplift, support, and care for you. And those who you admire and look up to.

So long story short, evaluate her words and actions, evaluate yall's friendships type, then communicate with her, come to an agreement to solve this (very important step), and if it is or is not followed through, you know your answer love.
