Is he with another girl or just needs time for himself?

Bre

So i meet this guy around July and for our first date he cooked for me he bought me roses and we continued to talk and see each other more often. At 3 months into talking he wanted to be serious and i wasn’t ready he told me he had feelings for me and we talked about taking things slowly and he agreed so we would hangout go out to dinner and stuff and just recently he invited me over to his house for dinner and we had a conversation about the possibility of me being pregnant but it came out to be i wasn’t i had told him that i had feelings for him too but i wasn’t ready for him to meet my parents just yet(he’s been asking to meet my parents) and the whole night we hanged out i felt like he was being distant but he would cuddle with me but his phone would go off constantly and then he told me he had to go and asked if i wanted to wait for him at his place and i said no I’ll go home and after i left his house it completely changed he would hardly text me back and after a day he finally texted me saying that he wasn’t happy with himself and before he made someone else happy he needed to be happy but he also wanted to talk in person i agreed to talk and it’s been two days and he hasn’t messaged me back at all but he sees my stories on Snapchat i don’t know what to do, do i completely stop texting him, do i tell him that i should move on, maybe he’s seeing someone else i just need advice on what to do and your opinion on this i don’t mind the negative comments it is what it is.....
