I've thought long and hard before posting (and namechanged because of the personal nature of my post) as there are other people in much, much worse situations but I don't have anyone I can talk to and I'd really like some MN advice please. I don't want to drip-feed so it's a bit lengthy.
DP & I have been living together since Feb 2011 and dating since Nov 2009. He is my first live-in boyfriend and first BF for five years. The same is true in reverse, except he hadn't dated for at least ten years and is forty, so has spent all of his adult life living with friends or by himself - I try really really hard to take this into account as, as difficult as I find living romantically with someone (just the niggles), he must find it worse. There is a sixteen year age gap, he earns over the average wage and is from a high income background, whilst I am still a student and from a low income background - we have had some hurdles to overcome here, i.e. what we both find acceptable spending levels/how much we contribute to household finances.
At the moment I am not earning as I moved 200+ miles to live with him and start my course. Without his contribution to the rent (he pays slightly more than half, we split bills theoretically evenly in a joint account, but in practice he pays a lot more for food as he buys expensive things I wouldn't) I would not have started the course as I don't have enough savings to support myself. I go home whenever the wages at my old work will outweigh the train fare. This is a source of resentment. I could get a job but DSis is lending me the money to complete the course (vocational, hopefully leading to a job - I am actively looking for one now in that field) on the condition I'd work for the best mark and not money. I don't have any of 'my' friends up here and don't have that many friends anyway. His/our friends live close by.
DP is from another European country and speaks English well but, as has become apparent when we have fights/strained discussions over important relationship things, not fluently. I think he gets so stressed he can't take in what I'm saying. I don't speak his language well - basic conversation level.
What it boils down to is that I'm insecure and when I've tried to tell him I'm insecure he acts like I'm mad to think so (and maybe I am). We are very physically affectionate but don't have sex as much as we used to, maybe once or twice a fortnight. I haven't broached this with him as I don't want one of two possible answers: a) that he doesn't find me attractive any more now I've put on some weight (which I am trying to lose, but not as devotedly as he would like) or b) that we are just two totally different ages for sex drives and he just doesn't have the hormones I do. If b is the case then I don't want to make him feel like he has to sleep with me. OTOH I was in tears (privately) earlier at the thought he finds me blimp-like and I really don't want to relapse into my old eating disorder (have had two relapses in five years).
I also don't know how to talk about the future with him. We moved in together after a painful row in which he didn't understand how I could be unsure about whether he wanted us to do so (he had said nothing on the subject and gave non-committal grunts to questions... I felt like a silly little infatuated girl by asking).
What I am trying to say is that I would really appreciate some advice on how to broach the sex issue (I am hopelessly shy at talking candidly about these things with him, although getting better) and how to deal with it mentally if the issue is my weight please. I would also like any advice from people with DPs/DHs who are in their thirties or forties about how he might be seeing things. He really, really hates talking - for example, he's being made redundant at the end of next month and refuses to discuss this at all. He talks about vague ideas but (as has become apparent over the past six months) these ideas are just what pops into his head to shut me up. I just want to help him and go through this together with him but don't know how. I love him very much and he has made my life so much better in so many ways. I really want to make this work.
