Finding lashes on his bed does not necessarily confirm that he slept with someone else. There could be various explanations for this, and it's essential not to jump to conclusions without further evidence or communication.
Possible explanations for the lashes on his bed could be:
Innocent Explanation: The lashes might belong to a friend or family member who visited him during the time you were apart. It's possible that they used his bed while staying over.
Misunderstanding: Perhaps there is a misunderstanding, and the lashes have a different origin altogether. It's essential to communicate with your boyfriend and ask him about it calmly and openly.
Infidelity: While this is a possibility, it's essential to approach the situation with sensitivity and not make assumptions without discussing the matter with your boyfriend.
To address your concerns and find out what happened, consider having an honest and non-accusatory conversation with your boyfriend. Express your feelings and ask him about the lashes in a non-confrontational manner. Open communication is crucial in resolving any doubts or issues in a relationship.
Remember, trust is a fundamental aspect of a healthy relationship. If you have concerns about trust or fidelity, addressing them openly and honestly can help both of you understand each other's perspectives and work through any challenges that arise.
