She Devil

So I recently just realized my boyfriends mom doesn't like me. I mean she doesn't say she doesn't like me, but I can just tell. When she's mad at him she won't say a word to me. She's ok with me picking up her son only if I swing by and pick up the younger sons. Which honestly pisses me off, like it's not my responsibility to get any of them really. I get my boyfriend because he's my boyfriend but their not my kids. And it trips me out like I do it as a favor, but if we don't pick up the younger one like 5 minutes after he gets out of school she's on the phone yelling at my boyfriend. He doesn't drive so 1. its not his fault and 2. its 5 minutes. Plus they live a few blocks from the school! Here's a thought, make the little boy walk! He's what 13?! Also, if my boyfriend goes out with me, there she is texting him nonstop. Its honestly rude and irritating. He's 18, we're at the movies, my house, beach, like he doesn't need to be baby-sitted. And one day I walk into the house just to say hi, and before I even get in she's like "sorry sweetie but its after 9 you have to go home". Umm, hi? Another day I cooked them breakfast potatoes for dinner, also there was some bacon and eggs. She gets home late, says "thank you" but then goes into the kitchen, chops up some cilantro and other crap and adds it to the potatoes and comes out with her plate looking COMPLETELY different from what I made. To me it was obvious she wanted them to be all "ooh and ahh; mom I want what you have", which they did, and it was unnecessary. I'm not trying to steal her family or become mom, I definitely have no interest with that. I only care about my boyfriend. Then to recently find out that one of his female friends doesn't want to go to prom and she offered to buy her ticket. Just wow; no comment. Last night me and him decided to go out to dinner. I went inside, said hello, he told his dad he was going out and we left to the car. We get inside the car and she comes over and tells him his dad is furious he's going out because he went out yesterday and he can't be going out all the time. I think this woman is waaayy to involved in her children's lives and needs to let go. I don't know how long I can deal, or is that what her motive is? Well hopefully when he goes off to college in the Fall this petty crap is over.
