Usually, when women speak of their husbands on this site as controlling, they mean something other than this.
I don't know if your current husband has an ex-wife or not, but let's suppose he does. If he spent a considerable (that's an important qualification) amount of time talking to his ex-wife, and they texted back and forth, would you possibly begin to wonder why on earth he divorced her and married you? Suppose he spent a considerable (!) amount of time on the phone with his friends instead of being with you; how would you feel about that after a while?
In maintaining that you don't spend much time with him, your husband is trying to tell you that he wonders if your homemaker work AND your communication with your ex are more important to you than he is. Is that so?
It can be amazingly hard to read signals (I say this from experience!), but please call a sitter to care for your children, and take your husband out on a date as soon as you can! Let him know how special he is to you. You've been actually married only four months; that means you're still newlyweds!
The laundry will wait, and so will the cleaning. Love won't (not in this case).
Also, try something secretly. Keep a little notebook with you, and jot down every day how many times you communicate with your ex. Journal how many minutes each day that involves, and make a note of what you talked about. Then try to cut that time in half.
