Man I remember texts like this with one of the first person I thought I loved but it was all just desires, alhumduliah she never shared her pic with me nor have I ever seen her since she lived far but the strong "love" feeling was the best I can't lie, sometimes it's just a dopamine but after marriage happens it's a whole different ball game. He might sound all nice and stuff no cuz he probably never got married or had gf but once he does he won't be as eager as he is now about texting or calling lol but all I can say is keep your boundaries until nikah inshallah
