At the start of this year I argued with my husband and stupidly sent texts to SIL to say could she tell her brother to take notice of me telling him I'm fed up of his behaviour which mainly involved him putting everything before me. DH and I made up our argument and weeks later I realised she was ignoring me and avoiding me. I've sent texts to her which are unanswered. I've apologised over text. I've texted asking her not to bear a grudge. I've asked over text why she's still ignoring me. Should I phone or try to turn up at her flat to get this sorted? WWYD?
