don't really know why

Hey everyone, I could really use some advice. I've been in a long-distance relationship for 2 years, and it's been tough, but worth it. I am currently working and my boyfriend just started college after stopping for almost 3 years and I'm so happy for him! But I can't shake this feeling that maybe we should take a break. With him meeting new people and experiencing new things, I'm worried it might be too much for our relationship. I trust him completely, but I can't help but overthink it.

Minsan di ko maiwasan maisip na nasa explore era or phase sya, maraming pedeng mangyari sa 4 years niya sa college and naisip ko lang na parang need ba namin magbreak up dahil baka makadistract ako sa bagong tinatahak or path nya ngayon? I trust him and I love him with all my heart and I am happy for him then nasabi niya sa akin na isa ako sa reason bakit sya bumalik ulit sa pag aaral. I can't stop thinking kasi about sa bago niyang environment, marami siya maeexperience, tsaka nag eexplore sya sa sarili niya. Don't know if I'm just immature for this or overthinker lol.

Has anyone else gone through something like this? Any tips would be super helpful.
