He told me that he was "trying to build a friendship with me so that we became best friends instead of him being best friends with someone else.
Wow. What could be better? A great friendship is better than a failed marriage. And great friendships can spring into great relationships. Work on that friendship with him. Be his friend.
So when H was talking about history repeating itself it was about how we started dating and became friends, fell in love and so on
Wow, again. Reminiscing over what made one fall in love with the other is a way that love can be rekindled.
He gave me the spare key to the new truck. Now I know he can take it back at any time but why would he give it to me in the first place?
Don't analyze. Instead, deal with results and outcomes. In this case, the outcome is that he gave you the keys. It is what it is. Accept that and keep going.
He said "No, I want to tell you. On the Saturday coming back from Indianapolis, when I sent you a text message and you didn't reply in the time I thought you should have, I realized then that I did miss you."
There's a clue to keep up the not replying in time in order to keep him missing you.
This week I have not done my best. I know the things that I did wrong.
OMG, good for you! Get rid of the things you did wrong. Good that you keep tabs on it and don't want to repeat it.
I sent him an e-greeting thank you card after he mowed the grass. It was cheesy, but cute and it just thanked him for mowing the grass. I signed it with the just the word "me".
Not romantic, not sentimental, just a straight, cute thank you with no embellishment. That's fine.
I took care of getting a wedding gift for our friends because he forgot about it - Am I being too easy by doing this for him?
He's a grown boy. If he forgets something he shouldn't, that's his responsibility, not yours.
I called him on an evening I knew he got home from work late and asked him if he wanted me to bring him something to eat.
What's the harm in that?
I sent him an e-mail telling him that I thought his new truck was awesome and that I was really happy for him as I wanted him to have nice things. Then I joked that yes I was a little bit jealous as he got to drive a big awesome truck and I was stuck with a stratus. I followed that with "need i say more" and a smiley. I'm sure he will laugh at that.
Nice. friendly. Humorous. It's not whiny, it's not about the relationship, so, what's wrong with that?
I know H is still in contact w/OW. Is it naive of me to put hope into those things that I feel are positives if he is still having a relationship w/her?
That relationship is going to go on for as long as it does and there's nothing to be done about it. That shouldn't stop you from doing what you're doing, and certainly, if he's showing positive steps, then there's seemingly a move toward you, isn't there? Don't expect big major changes. Little changes are the reality.
Do WAS who have an A go through a period of time when they are still having a relationship w/the OP but they are having a change of heart towards their spouse and seriously considering returning home?
Oh, I just answered that, didn't I? You'll be the last to know after he's made his decision.
Or is my H just telling me what he thinks I want to hear so he can be my friend and continue a relationship w/her as well.
Time will tell. Watch and see if the positive steps continue.
I have heard it several times (from non-DBing people) that H is not going to come home when he can "have his cake and eat it too".
