Bullied by a Friend, Long Story.

So, last weekend I attended a birthday party hosted by a fellow Indonesian friend, M. M asked me why I never show up in the church again for the last 3 months. She then asked me if my not going related to a friend named L. When I first came here, L is the only person from Indonesian church in my area, so she offered me a ride back and forth. But me and my hubby became uncomfortable because she insists my hubby play music and I become the sunday school teacher. We just think that if we want to serve, it should be from heart not because threats. As a senior, she kept telling us that God will take away our talents if we don't do it, or God will be mad to us. Last time, she made us isolated by not taking us to any fellowship which she made obvious because she posted it in facebook. I am a newcomer here,so you can imagine how we feel.
Finally, she made me babysat her toddlers when she did the church music rehearsal. It was like 4 times, and it was long babysitting. Once, she made me babysat her toddlers for 8 hours and she turned out at 11 at night. The reason I do it is also because I feel,pity on her babies, too. They seems like lack of mother's affection and I ( stupid me) wants to be the fairy godmother ( I know, silly!). With 3 kids, my house was a mess.
And when the winter was here, everyone was talking to go to flagstaff, the snowy mountain in az. We never see the snow, so when L took us there we were so happy( we have no car). I paid for the whole family meal,though. So it was quite equal, like she has the car and gas and I was on the meal.
However, a month after the snow trip, she texted me like this :( it was our last trip together)
L : do you bring my jacket ?
Me: No, what jacket?
L: My black favourite jacket. It was on the trunk and you had your stuffs on the trunk with my stuffs, too.
Me: No. I didn't. If I happen took ur jacket, I will return it to you.
L: So what should I do? It is my favourite jacket.
Me: I don't know. When did the last you time you saw it?
L: The flagstaff.
Me: Are you sure you don't bring it to other place?I never took ur jacket. I think I saw you with that in Helen's house. Why don't you ask her? Have you?
L: No.
Few minutes ago she texted me like this:
It was in Helen's home.
Me: Oh, good.
L: For your info, I only asked, I didn't accuse you, okay.
Me: Yeah, okay.

I was really mad and I believe she sensed that. But, she still had the guts to ask me babysat her babies for a whole day. I said no, and she asked why and why and why. I never go to that church again. But, of course I can't always avoid thebirthday invitation from others member, so I went. And this is what I found in yesterday party.

L told M about the jackets incident and she told her that I am a high tempered person because she didn't accuse me only asking. M told me that don't take it seriously because generally people will always have this small conflicts because even siblings can fight so do friends. But she was shocked when I told her how L threatened us about church service and the long babysitting. She told me that L made people pay for her babysitting and the rate was high. So, she was shocked knowing that L never pay me (once, with a bucket of KFC fried chicken). Idk if you babysat, you will be paid. It was quite common in my place to babysit, but not that long, too. I met her in the party, and she was not happy saw me there. M was interrogated why she invited me. Idk why she did that. It seems like she wanted to isolate me. But why, I don't understand. It was not a good bargain position for me. She was the senior here, I am the youngest. People will be prone to believe her, after all I am a newcomer, not a churchgoer, not someone who can mingle with them( no car), and poor students wife. Especially yesterday, when she saw me taking pictures with a camera. She looked at me with anger. But why? My camera is the 90 dollars sony on sale, hers is the big one with lens. What should I do? It seems like she twisted the story, and I must clear my name.
My mom told me to stay away from this Indonesian community, it is not healthy she said. What do you guys think?
