I need some advice on how to navigate this with my boyfriend as I struggle to express how it's making me feel. I'm 47 hes 50. I've 3 kids between 10 and 23. He has 21 year old that lives abroad ( educational). He works 3 hours away, 4 days on 6 off. On his off days he's with me and my children. We have had issues regarding his ex before. I was going through my divorce but he'd not even started his and it was a touchy subject if I brought it up. He got therapy and started the divorce. My issue is when hid son returns from abroad for a week or so im not allowed to meet him and when he spends time the ex wife is always there. Meals, days out...he doesn't get the time with him alone to even be able to introduce me. His son stays with his mum when she's back and gets to see her son everyday but any time with his dad it has to be as a family unit. This is making me feel like im an outsider, hes involved with my life but I'm not his. Never met his friends, his sister either. His son is back now for a week and brought his new girlfriend and I suggested he introduced me too. No. Apparently this makes me rude and selfish when he's only back for such a short period and I'm not a priority. Am I in the wrong for feeling like a spare part? We have been together 4 years almost. I just don't get the seperated lives. He talks about his son and everyone else in his life, I feel I know so much just never spoken or met any of them. Thoughts ?
