<human>: Can you give me the gist of the text in a nutshell?

The title pretty much explains it. I've been with this guy for a few months now and things have just now started getting more serious. He's asked me to join him and his family for thanksgiving and had included me in the name drawing for Christmas presents his family does. 

When we first got together he was still dating this girl that he told me he was having a hard time leaving because she apparently has some serious mental instability issues and was desperate to keep him. But he did leave and we started dating pretty soon after.

So on Monday he messaged me letting me know that he was working late and going to bed early and that it would be a good night for me to get out with some friends. So I did and thought nothing of it. The next day he sorta starts asking me who I was with the night before which was weird. He apparently doesn't like a certain person I was hanging out with and I told him that if he had a problem with it then he needs to let me know. He said he wasn't going to do that because he doesn't want to tell me who I can and cannot hang out with. He also said he doesn't want me to change anything for him...??

So last night he handed me his phone to call a cab and her texts happened to be up.  I saw "I had a good time on Monday" and  started reading the rest. Apparently they went to the movies on Monday. The night he told me he was staying in. I confronted him about it and he gets defensive but eventually started apologizing. 

The kicker is that he took me to the same movie two days later and acted as if he had never seen it before. 

He's asked me to forgive him and is saying that he would never do anything to compromise what we have and that he's falling in love with me and that he will never keep anything from me again. 

It's the calculating and deliberate lies he told me that are bothering me more than anything else. I really just don't know how to feel right now. Should I even try salvaging this?
<bot>: My boyfriend took his ex to a movie after lying to me and saying that he was staying in to sleep that night. He took me to the same movie two days later. Pretty shameless.
