It can be frustrating and disheartening when you feel like you're making an effort for someone you have a crush on, but they aren't showing the same level of commitment or loyalty to you. Here are some steps you can consider taking:

1. Communicate your feelings: Talk to your crush about how their actions make you feel. Be honest and open, expressing your concerns and expectations for the relationship. Make sure to listen to their side of the story as well.

2. Evaluate the situation: Take a step back and analyze the relationship objectively. Are you both on the same page about your feelings and expectations? Does your crush even know how you feel about them? It's essential to have clear and open communication to avoid misunderstandings.

3. Set boundaries: If your crush is consistently sneaking around with other people while you're investing time and effort into the relationship, it might be necessary to establish some boundaries. Let them know what you are comfortable with and what is unacceptable to you. If they continue to disrespect your boundaries, it might be a sign that they are not as invested in the relationship as you are.

4. Focus on self-care: While it's important to care for your crush and be there for them, it's equally important to prioritize your own well-being. Make sure you aren't neglecting your own needs and happiness in the pursuit of someone who doesn't reciprocate the same level of commitment.

5. Consider moving on: If your crush continues to disregard your feelings and engage with other people despite your efforts, it might be time to reevaluate the relationship. Ultimately, you deserve someone who values and respects you. It can be challenging, but sometimes it's better to let go and find someone who reciprocates your feelings wholeheartedly.

Remember, it's crucial to have open and honest communication, set boundaries, and prioritize your own happiness. Relationships should be built on mutual respect, trust, and commitment from both parties.
