<human>: Can you condense the text into a few key points?

Hi guys, I'm hoping somebody can offer me some advice. My husband has had a rocky relationship with his Mom for the past 2/3 years. It sort of correlates with when he moved out of his family home and in with me. We moved about an hour and a half away and we used to see them once every week. I'm not really sure when the fighting started or why (I think hubby is keeping it from me). They just seem to talk less and see each other less. When they do its a fight over how hubby has changed and doesn't respect her anymore. 

Anyway the passed few days they've been arguing through text message and I think it's getting out of hand. Hubby says MIL mentioned about cutting each other off. He says she's being dramatic but he refuses to call her or invite her down to talk through things and fix them. 

I don't want to get in between them and I know I don't know all the details but I want this sorted and fixed. I feel my only option is to call MIL myself and see if I can help things. 

My hubby wouldn't lie to me or keep something from me usually. All I can think is that he's sparing my feelings and MIL actually blames me. 

I'm sorry this is really mixed up but I'm really confused as to why this is happening and how to fix it.
<bot>: my hubby and MIL are arguing about me and I don't know whether it's appropriate for me to get involved and contact my MIL.
