I am so hurt and just want to vent

The kids and I travelled abroad last Thursday as I have something important to attend to. We are not due to be back until next month. Since then my partner either takes hours to reply me, doesnt pick calls or even responds initiate text messages. I tell him about my day when we get to talk and he doesn’t even tell me anything. When I message him and it doesn’t deliver for hours he then replies that he was out. This morning I decided not to message him as it’s been a chore getting him to reply me. He haven’t texted me either and he is actively online. I feel so hurt and unwanted. My mind is so busy thinking of different things. Thinking of what if he is with a woman and that’s why my messages won’t deliver or won’t pick my calls. I am having sleepless night and have no one to talk to. I told him and he doesn’t even care how I feel. I had a dream overnight and so sacred it’s what’s happening as my dream comes to pass
