Hello there looking for advice partner and I have been together nearly 13 years and have 3 children 3,2 and 5 months. At Christmas he introduced me to an old 'family friend' (One no-one had spoken to in well over a decade). I was picking my partner up when we were introduced. The guy decided he HAD to come and have a look at our home to 'check' it for any areas that needed fixing??! I said no but partner obliged anyway. He wanted coffee and we had none so was sent to get some from shop. After handing him a cup of coffee he said he would be stopping for at least 5 cups ( I thought he was joking - he was not) This man was loud, obnoxious, and did not know about personal boundaries. He kept putting his arm around me and demanding kisses on my cheek (I'm quiet and shy, unable to say no partner also did not say anything despite knowing i was uncomfortable) he kept demanding things, swearing and he spoke so loudly it scared the kids. After he left I said I didn't want to see him ever again . 6 months down the line he's started showing up again and I said to my partner that I didn't want him around the kids or me. My partner said luckily he has 50% of the say and if he wants the kids to see him they will. Please help with opinions. Thanks in advance
