My fiancé and I have been together for two years we have a beautiful little girl together and I love him with all of my heart, but when we're around certain people he acts different, he puts me down and stuff, and he acts like I am second to everybody like I am the last person he cares about. WHY?

Does he act differently if it's just the two of you? He is just joking and would like to show that "he's the man" only you're hurting. You have to communicate this to him so he would know.

If he's the same with or w/o people, then it's time to think again if you want to end up with this type of man.

I know your still young, and adjusting to things, but he does what he does because you let him.

Speak to him calmly, and
1) find out why he does it and,
2) make sure he knows how it makes you feel when he does it.
3)Then you can tell him don't think he can "F" with you that way in public, or any where else.

Stand up for yourself.
