so me and my bf have bin dating for like 8 months now are relationship has bin good I love him so much and so do my kids about about 3 weeks ago my bf went to vist a family member and they told home they think he is just settling for me cuz he should be with a "bader bitch" than me and they got in to a fight about it after that he has bin a little distant with me and then we had a conversation and he said a fue things that was a isue with are relationships 1was I'm getting to comfterbal with I don't get how that's a problem I feel like you should feel comfortable in you relationship 2 was are sex was boring with is true but every time we have sex he wants to do the same 2 position 3 was that I'm emotional with is true but i dnot know how to turn that off its how iv always bin but I told him I would try 4 was that we go out to drink together and he's tired of that( we haven't gone out to drink together in like a month or more be for he ever said this ) but his reasoning for not wanting to go out and drink any more is because he's tryna get a heather life style and drinking isn't part of that but the a fue days after he said that went out and spent hours at the bar with his friends so wile we were talking about what he felt were things that were issues for him in are relationships and me coming up with ways to make them better he tells me that he's not as attractive to me as he was when we first started dating because I gained 15 pounds witch i have but I also started taking birth control so I told him I would start eating healther not just because he said my 15 pounds was a problem but because I lost 80 pounds be for we ever met I don't wanna gain it back so I need to go back to eating she way I was when I lost the weight in the first place now my issue is be for he ever went to see his family member and them saying this are relationships was good happy and now its a little distant but I don't get why why is all this a problem now like it all came up and changed a day after he got back from seeing his family member who I have never met they have only seen pictures of me that he has posted on social media what do yous think???
