Manipulating or Good Intentions?..Comment but dont be rude please!

Okay so...

I am 24yrs old and ive dated my SO for 6 years...Before this we were bff and our relationship was the best! Now we have a 4yr old ive mc 1 time. And did i tell yall hes the only child...

His mom is always in our business... and she always trys to challenge me in all that i do.Okay so we moved in our first house and we are young so its hard but i feel that its supposed to be ya knw makes you appreciate what you have ..

Then one day he comes home tells me hes going to buy a new truck. im like huhh?? new truck? how? He claims his mom brought it with her own money.. Meanwhile two weeks before that i find out he has an account with his mom i knew NOTHING ABOUT! I lost my job about a month ago so hes been paying everthing but before this he couldnt keep a job so i was sole provider for . Now every time i questioned him he tells me to get out hes better without me and all this stuff. but i feel stuck because i literally have nothing no money no nothing and hes done this before but i gave him benefit of the doubt and tried us again. I feel so dumb and helpless and i have parents who could care less whether im alive or dead ...i just need some feed back please
