Help please πŸ™πŸ»πŸ™πŸ»

So I’m really struggling i was away with my boyfriend for a couple of days for a car thing that he really wanted to go to and then came back for a friend of mines wedding, which i said he didn’t have to come to even tho he was invited. Now at the car show he kept forgetting i existed like driving away with me half in his car and going whoops or leaving me by my self at someones house or walking away at things so i was walking by myself. He kept making the most disgusting sexual jokes and comments. We then left to go to the wedding and he was all lovely in front of my parents with his arm around me etc and lovely and polite and chatty and the second they leave he like ignores me and plays on fb and gets grumpy at me for wanting to stay and dance with my friend. Then gets grumpy about having to drive home late even tho neither of us had work the next day and only grunts at me in the car cuz hes β€œso tired” and then get home we both get into bed ive taken my sleeping tablets and he says are you going to sleep i said yes i am nearly there to which he preceeds to have sex with me while in sleepy as :( now heres where it gets tricky i have talked to mum about this and she said she said i need to get over it but it happens all the time and its really starting to hurt πŸ₯Ί
