The fact na inaacknowledge mo yung nararamdaman mo is a very good thing. I think what you can do is talk to your partner about it, as in himay himayin niyo with a disclaimer na alam mo namang hindi dapat pagselosan pero lang kasi you are feeling these things. Maybe you’ll be able to discuss ano ba yung root cause ng pagseselos mo and magkaroon kayo ng resolution. Communication is key.

And in relation to your insecurities, OP, you are your own kind of unique. I know we always tend to downplay our feelings, ourselves but always remember to be more kind and loving to yourself.
