Are we breaking up or is he playing mind games with me?

I'm at the end of my tether, foreign partner 'M40' hasn't been in contact with me 'F46' has he left me or playing mind games? Foreign partner 'M40' and myself 'F46' had had a beautiful relationship of 7 years together, until his children moved in with us last year, I tried to do my best but it was never enough for the kids. Now his kids wanted to move back to their own country to live with Mom and they've blocked me from everything. My partner returned and has became so distant, it's breaking my heart as our relationship was solid until his kids moved in and became very demanding. I've tried contacting my partner for 3 days but nothing back. He's got his own home just a 2 minute drive from mine, he left me the keys, now I don't know what I'm supposed to do? He's receiving benefits for his 3 kids but hasn't cancelled anything with benefits and housing, I don't know what to do, he's left me in such a mess. Do I contact benefits and housing on his behalf as they've been gone since April we're now in August, his home is fully furnished should I clear it out? He's been back a few times in the UK since April but not the kids. When I try talk to him he keeps saying he'll get everything sorted but he never has. I'm scared and don't know what to do. Please help. 😔
