I'm not sure where to start, but I'll try to be brief.
About 2 years ago my sister started an affair with another man (she's been married 20 years and has 4 boys). It was kept secret for about 6 months, then her husband found out and she said she would end the relationship. She loaned money from my parents so she and her husband could go on a week's holiday to try to repair the damage. The entire time they were away on holiday she continued to text and email her lover (who, incidentally has a wife and 3 kids).
After the holiday she continued the affair whilst her husband thought they were trying to make a go of it. All the while she was hoping her lover would leave his family so they could start a new life together ( but she wouldn't leave her husband properly, keeping her options open)
Her lover lives in a different city, so she told her husband she had to move to that city, because it offered a better arts course she wanted to do(despite the arts course in our city being exactly the same). I don't know why (I imagine he was trying to help her "find" herself)but her husband was very supportive of this decision. It meant that she lived away for two weeks at a time and would come home, to her children and husband for a weekend every two weeks. Her youngest two(2 and 3) children were put into full time childcare because her husband had to keep working. The arrangement meant they were paying for her accommodation and other living expenses in the other city.She didn't work to help out financially.
Eventually she dropped out of college because she was actually spending time with the lover, not doing the coursework.
During this time she would call me and cry on the phone for hours because her lover wouldn't make a commitment. She got pregnant and he "made" her have an abortion (or he'd stop seeing her).I listened to her tales of woe for many many hours.I was patient and loving and tried not to be jugdemental.
Fast forward to now. She has moved back to this city, but goes up to the other city at least every two weeks. Her excuses range from seeing art shows, seeing specialist doctors, catching up with friends, seeing music shows etc. I think because tension is high at home, her DH happily lets her go. But she is still having the affair, despite the lover getting less and less loving, and giving nothing more than the occasional shag.
My problem is I'm not sure I can maintain my relationship with my sister. I can't condone how she is destroying her marriage and hurting her husband and children, and swearing me to secrecy. I hate that she just drifts, makes no financial contribution to the family and despite not having a job sends her two youngest sons to daycare everyday.Her selfishness is starting to make me feel angry. She has no time for me except when it is offload all her problems.
She's had loads of couseling, then comes and tells me it is all our parent's fault that she behaves this way. I wish she'd take some responsibility for her actions.
God, that was long. So sorry, I guess I really have compassion fatigue and don't know where to go from here. The last straw was when I phoned her this morning, she wouldn't answer to talk, but texted telling me she is too busy, eventually saying "I have fucking stuff to do you know".
Should I give up? Distance myself from her? She lives quite near me, but I can avoid her if necessary.
Often after seeing her I just feel tired and annoyed.
