MLC step by step...what's next?

[Lilith]

It's been awhile now since my last post. 'Been quite busy with work and GALing...though nothing much changed really with my sitch. I'm not sure either whether there is progress in "me"...and I have a feeling that doing dim hasn't or isn't doing anything to improve our R.

I was actually feeling "OK" this past weeks except of course for some days that I'm feeling so alone and lonely and missing H so much. We talk (but purely business) and get along well at work.
During father's day, S22 asked me if it's alright with me to invite his dad to come over for BBQ,I said why not?..so he came by and we had bbq the three of us. He seems relaxed and enjoyed the family meal. We talk things like;... work, business, our friends, family, neighbours etc. except about "us" or about his life being alone (or with OW) or me being alone/with our S. He asked how things here at home (domestic problems) but never ask how I really am doing. I guess he really doesn't care even a tiny bit about me anymore and I feel sad when I think about that.

Few weeks back he mentioned he was going to come on a saturday (tomorrow) to help me & S22 clean up the garage and bring the garbage and old stuff waste to the container park. So, this morning he said he will be at home around noon time so I asked if he wants to join lunch with us then? He declined. Not that I was really hurt (because I prepared not to have any expectations)...but I just get annoyed when he tries to explain & makes excuses which is obviously very lame excuses. Why can't he just be honest!!!
So, now I was wondering if my casual/friendly invitations would be considered as pursuit? Should I stop asking or inviting him?
