I would like to know what you would do in this situation...
X and exgf broke up with him whilst they had 5 month old. Person X did not take this well and though ex-gf changed mind about contact he ended up doing as initially offered turning up at house even though she advised not to turning up to parent's house ect. Ended up calling police for harassment and X did not see child for few months now has regular contact as issuing proceedings in court. This was four years ago but person X holds exgf totally responsible for situation and will not engage with her on any level, constantly talks bad about her, constantly wants one up on her or thinking of ways to annoy her. Constantly looking for ways to catch her out. Jumps at every chance to make difficulty for her and issuing proceedings in court against her for contact says things like shes going to end up losing kids (even though she has done nothing to suggest this in particular) and going to end up selling car to fund solicitors and also says not nice things about her other kids.
Finding it hard to side with this person and agree with stuff they are saying. My thoughts are to distance myself from them even though close friend in past. AIBU?
