Ignored..

Me and my boyfriend have only been together a few weeks. The other day i was upset about him not spending much time with me and i made him aware of it. In the middle of the conversation he stopped answering. It’s not been 48 hours since he has texted me back. He hasn’t answered any of my texts or phone calls. Should i just assume we’re broken up? I juSt don’t get it.. it wasn’t some huge fight i just told him how i was feeling.. 😞 he’s 35 years old i thought he would be a little more mature then this.. smh
