Hi there, firstly i would like to say sorry for going through a rough patch with your partner. Losing a mother is very painfull so your partner is going through a very difficult time in his life, I really think you should be there for him,well he might be harsh at times but you must be patient he will come around. he is in a grieving stage and he needs somebody to hold his held and be there for him. well for now he may push you away jst dont push back. I really hope things go well between the two of you.
