Thanks for taking the time to share. I want to encourage you with your boyfriend to experiment with finding ways to be kind to him. I'm not saying you're not. Just try something this next week. I think you may find something coming back to you! Every day ask yourself the question, "what can I do to bring him joy?"
It may be simple things. Why do this? This may bring some spark back. Your boyfriend may be feeling the stress of life and is taking it out on you. So, for the time being, see how you can lighten his load and put spring in his step. This may not work but then again it may and you may have fun doing it!
Start with seeking to find out what he appreciates:
-verbal affirmation?
Tell him he did a good job at something (has to be true).
-quality time?
Do something with him that he loves: like watching football or whatever (even if it's painful- within reason). If he likes to talk, ask him about his favourite subject and be seriously interested or this will backfire.
-physical affection?
if he loves this, even a simple shoulder rub is delightful and he feels like a million bucks.
-gifts?
what little thing would he appreciate?
For now, if your boyfriend is not listening to your feelings, share them with a girlfriend for the time being. Like I said above, he may be feeling the weight of being a father and provider. There's a lot of stress a guy takes and often we women tend to forget this.
So, experiment with lightning his load and tell me how it goes. I think you may find an interesting change in him. It works for me and my man anyway. I tend to forget about his needs - hey we all do - we are human. But, when I seek to show him he is valued, I get cherished too. But, I must have the right motive. Give to give, and not to get.
What about your load with your beautiful new little girl? See if you have friends or other family nearby who can help who are happy to do so. This may help to take the stress of him too and of course you!!!
