How can I be sure my partner truly loves me and is not playing with my emotions?
My first question would be, what makes you think your partner is playing with your emotions? What behaviours and statements allow you to draw this conclusion? The mind is a very difficult tool to work with and it’s extremely hard to see reality without the layers of storytelling that the mind creates. That’s why it’s always important to communicate and share your concerns. Nevertheless, be factual in how you approach things, whilst still sharing your feelings, to avoid sounding like you’re blaming your partner.
So, for example, tell your partner that when he does or says x, it makes you feel used and unvalidated, and you need someone who can appreciate your emotions, so would they consider stopping or changing x? The more you talk about these things, the more you’ll get to know each other and what really works for you both.
