I JUST DONT KNOW WHAT TO DO ANYMORE
My mom met this guy in 2010. Things were rocky from the start. At first I was jealous cause it was the first guy in my moms life since I had to tell her that my dad was cheating on her in the Christmas of 2005. so for five years it was just me and her. then we got in a fight in 2011 and he kind of got physical ripping my head phones out and braking them cause he though I was ignoring him but I thought he just stopped talking. it took a really long time to move past that. Since then we have had our ups and downs. I have been quite protective over my mom because of what my dad did to her. So often it comes across as I don't want him around when I am just looking out for my mom. I am trying to work through that but its really hard. He wasn't there after what my dad did to my mom. it was just awful my mom was a mess I ended up having to grow up really fast I went from 10-20 years old over Christmas. I was the rock holding my mom together. so I don't want that to happen again.
so he loves telling jokes, puns and at first I didn't mind but lately there getting real bad. there constant even if there totally unrelated. the worst part is there just awful joke or puns Thanks to his jokes I can't take anything he says seriously. It's annoying and constant every time he opens his mouth it's flipping joke. And a lot of them make no sense or I don't even know what he's talking about and he interrupts everything just to get a stupid joke in. its seriously getting on my last nerve. I have been putting up with his lame ass jokes to long. My mom won't even let stand up to him. And every time I talk to my mom about I hear the same lame ass excuse "It's who he is. He can't change" I just can't take anymore!!!!!!!!!
That excuse is pure bull shit. She just says that lame ass excuse every time and then she turns it's so its my fault I feel like a ticking time bomb tonight I finally snapped and really lashed out. so tonight he was making some TV show theme song all about him and I told to just stop it in a frustrated tone. It's all about him.
plus I have been real moody and snappish lately cause I stressed with finals at university.
plus he acts just the whole world revolves around me and I need to be the center of attention. he is always trying to one up me so he gets all the sympathy. its so annoying. some of his jokes are just plain mean. I think that's why he tells so many jokes cause he cant stand not being the center of attention. he doesn't care what kind of attention positive or negative.
plus he does have a really hurtful habit of making me feel stupid if I don't know something.
I tried talking to my mom she wont hear it at all. because it all my fault and I am the embarrassment. its like he's Mr. perfect. also on countless occasions I tried to get me my mom and her boyfriend in for a counseling session with my therapist but all I hear is no its waste of time and money. I am the only one with issues, I did everything wrong.
I know I can be snappy and moody and have a short temper some days and I sometimes treat him like dirt I will admit it and I have said sorry many times. I have at least tried to change where he gets off Scott free and never as to change.
I am feeling like he gets away everything I rarely hear I am sorry from him
I really at the END OF MY ROPE. don't know what to do because he's really mad this time and so is my mom. and I am going to blow up if he tells another joke. how do I ignore the things that make me crazy?????????
HELP WHAT SHOULD I DO
