Husband left 🙃

To give background on this

My husband and I of 2 years are separating . We live with his parents and we have a daughter . We can’t communicate we are on two different levels when it comes to everything . So this week is his birthday and his parents left weeks ago to Florida . He left on Monday and will be there for a week to “celebrate”. I couldn’t go because I could not get off of work. I asked could he wait until next week and he said no. So since she’s been gone and I have our daughter it’s been on my mind that he really left us back at his parents home . While he and his parents are vacationing . Am I wrong to feel this or is he wrong ? Like I get we are separating fine but we are still family .
