What to do...

[Lindsey]

One more big blow-up last night. She sat on my lap for a couple minutes and he snatched her up and put her out of my room and slammed the door. I asked what was going on because she wasn't doing anything, and he said "She was making me mad. She was sitting there staring at me" So I guess it really is just anything now... we fought for hours and he kept saying "Is there even a point? Is this going to work out" and I told him "I'm not forcing you to stay here, or to stay with me. If you can't handle this, you can leave, and you don't have to be with me." and he turned it around and said "Is that what you really want? You want to just break up with me over a dog?" eventually we just both got tired of fighting and crying and he cracked a smile and told me he's sorry and i'm beautiful. This morning he left my house all happy, but I can't stop thinking about it. I just sent him this email:

Hi. Well I really don't know what to say here. I'm not trying to be grumpy and I'm not mad. I've just been thinking about last night. I wouldn't have gotten into this relationship at all if I thought it wouldn't work. I don't put a friendship at risk unless I really really like someone. I didn't see this coming, all the fighting. It just came up out of nowhere. Why did you get involved if you knew this all before? You and Ryden had talks about my dog, you've told me that. You knew the situation before you got into it. You even said it just kept building up over the whole time, so why didn't you just stop when it started bothering you? Is she really the whole problem here?
If you're already thinking that this isn't going to work and it's not worth working on, then let me know. I do really like you and I want to be with you, but sometimes I don't want to deal with all the frustration I feel from fighting over and over about the same thing. I don't think we've gone a week since we've been dating that you haven't asked me if I'm dumping you yet. I just don't feel like you have much faith in us.
I'm not going to break up with you. You can let your little wall down, and just accept me and accept being with me. And if not, then you can take the next step. I don't want to keep rollercoastering like we have been.
I guess that's about all...
