Aw bes, totally normal yan lalo na 18 weeks pa lang, ang hormones mo ay all over the place, plus ang insecurity na dumating with the pregnancy changes, na sobrang valid naman talaga! One of my mum friends was the same during her first pregnancy, and napansin namin lahat na it wasn't really about him being unfaithful, it was more about her own fears about her changing body and what that meant for them, kaya try mo lang talk to him calmly pag hindi ka emotional, like, "babe, I'm struggling with how I look right now and I need reassurance" instead of accusing him, because honestly it helps a lot more. The seeking reassurance part ay okay, but if you're already at the point na gusto mo lagi siyang makita para ma-reassure mo sarili mo, baka need na mag-reflect ka on your own self-worth din, hindi lang based sa attention niya, easier said than done, I know, but it really does help the relationship and your peace of mind! Prayers na ma-process ninyo to together and na mas mag-relax ka towards the second trimester, mama.
